What is included in the kit for the car and preparation for sale. Car equipment

The market for new cars in Russia today is huge, there are always many interesting offers for a buyer with any wallet. Perhaps the most tempting for most Russians are cars in basic configurations with a minimum set of options or none at all.

However, being tempted by such a car, the buyer often encounters a problem: the car is not available, the waiting times “on order” are frightening, and the manager insistently offers to purchase exactly the same, but in a more expensive configuration. This situation, familiar to many, is by no means a coincidence, but the result of an accurate calculation.

Is there a basic package at all?

car in basic configuration- the beginning of the countdown in the price list of any car dealership. Such cars are also called "empty" or "naked", because the options in them are at a minimum. Although for some models this minimum is not bad: air conditioning, ABS and, for example, front power windows.


Due to the difficulties in acquiring such cars, some buyers tend to believe that there are no cars "in the database" and this is an invention of dealers. However, experts assure that such cars exist. Only there are very few of them and they are intended not so much for sale as for attracting buyers to car dealerships with their price tag.

That is why such machines are usually not available. Or the waiting time for their delivery is so long that many buyers would rather agree to the more expensive option offered by the manager from the warehouse than wait. And all because it is unprofitable for automakers to produce cars in the basic configuration - the profit from its sale is minimal. For this reason, base cars are assembled in small quantities - on average, about 2% of the total production of the model.

Rules for “hunting” a car with a minimum configuration

But you can still buy them. For example, if the demand for a model is low, then finding a car in the basic configuration from the seller will not be difficult. But if the model is popular, then the car will have to be hunted. In addition, some dealers complicate the search for basic cars and complete them with additional equipment for profit. But do not despair if the desired car is not immediately found. Deliveries of new cars from the factory is a constant process, and the waiting time for a patient buyer is not a hindrance.

Most the right way find new car"in the database" - call as many car dealerships as possible, where the desired model is sold. This will help you find out if the car is available or you will have to order and wait. If one of the sellers immediately offers to buy base car, but with additional equipment, then dealers have cars. It's worth seeing this one in person. It is highly likely that the "additional steps" on the car have not yet been installed and, perhaps, it will be possible to agree with the manager to sell the car with a minimum number of options (and floor mats). At the same time, you can see if there are still cars in the parking lot in the basic configuration, which the dealer is silent about.


It will not be superfluous to leave your contacts to all car dealership managers with whom you will communicate in the process of searching for a car. The option is not ruled out when someone refuses the desired car and then the car will be offered to you. Also, an offer may come from a seller who, at the end of the month, will need to urgently sell cars to fulfill the sales plan, even with minimal earnings on them.

There is reason to pay attention to major dealers. In terms of total sales, they surpass other car dealerships, and therefore the cars are sold in more. So the probability of finding the desired basic equipment among fresh deliveries is higher. To obtain desired car faster, it is better not to opt for a particular body color. For example, during the search and waiting for the red base Logan, the seller can receive five of the same blue or white ones from the factory.

By the way, do not get hung up on finding and waiting for the cheapest option. Sometimes it makes sense to choose instead. Of course, it will cost a little more, but the overpayment may not be so big if the order is expected to be six months or more. Cars from dealers sometimes rise in price up to twice a year and, perhaps, buy basic version with automatic transmission will immediately cost almost the same money as a car with "mechanics" a few months later.

Buying a new car at the most favorable price not as simple as it seems. But the "profit" from such a machine is worth the time spent looking for it. More likely to succeed are persistent and active buyers who spare no effort in calling dealers, visiting car dealerships and negotiating with sellers.

Since the base car is a product that the dealer most likely will not want to sell without earning anything on it, be pushy and get what you want from car dealerships. If you suspect that the dealer is lying to you, contact Russian representation stamps asking for help and assistance. Write complaints about managers who do not sell cars without “special stages”, call hotlines - such activity will definitely give results.

We will talk about such an important thing as car equipment And additional options.

Now everything car brands offer their customers a huge list of options. Let's try to figure out which of them are really needed, and which ones you can do without. We will review the list basic options, which equip modern cars and choose the most useful and essential of them.

Auto kit. Choose a package

To choose a package First, let's define terms. What is car equipment and what are they?

Basic configurations- these are standard sets of options, on the basis of which the buyer configures his future car. When ordering a new car, the buyer must choose one of the basic configurations, and then add to it available options and option packages. You can do all this in configuration configurator, which is on the website of each automaker.

For example, the Ford Mondeo configurator offers four options basic configurations:

  • Ambiente
  • trend
  • Titanium
  • Titanium Plus

Minimum equipment auto is the simplest of the basic configurations, having the fewest options and the most affordable. For example Ford Mondeo minimum is the basic equipment Ambiente. Respectively, maximum- This Titanium Plus, which includes almost all possible options.

In fact, friends list all options all brands of cars - just physically impossible. Each automaker is constantly coming up with something new (marketers know their stuff)). For some models in the list options in general, you can find such funny things as " increased ground clearance " or " suspension adapted to Russian roads "")). Here you need to understand that in fact people just praise their car model, and all these features are not a real additional option.

The most useful equipment options

So, friends, what are additional options, we know. Some of them are quite useful, others are more of a luxury, but there are options without which it is better not to buy a car.

  • Air conditioner
  • Front power windows
  • Additional crankcase protection
  • Winter options
    • Heated side mirrors
  • Front and rear sensors parking
  • ESP stability control system
  • Central locking, alarm and immobilizer

Let me explain why I think these options needed.

Air conditioner

Air conditioner in summer you need no less than a stove in winter. In good heat, in a car without air conditioning, you feel like in a microwave. In my opinion, it’s even unsafe when the driver’s brain overheats from the heat, and it’s not far from an accident.

Minus air conditioner in that it simply cools the air, but does not regulate its temperature. If you don’t follow the air conditioner, then it can cool the air in the cabin too much and then it’s not far from a cold. Therefore, the ideal option for you will be climate control- a system that controls the temperature of the air in the cabin. Climate it is more expensive, but it automatically maintains the set air temperature, which means it creates comfort and at the same time saves your health. In my opinion, climate system - This is one of the most necessary things in the car.

For a healthy strong man, an amplifier may not be necessary, it rather increases comfort, but for women it is better not to buy a car without an amplifier at all.

Absence amplifier especially pronounced in the parking lot, when you have to turn the steering wheel and pedal. Of course, Parking is much easier with booster..

Front power windows

If you can somehow do without rear windows, then the front ones are real necessary thing. Now front door windows put even in minimum configuration but if you get old car without front power windows, then think again: are you ready to turn the handle every time to open the driver's window?

Additional engine protection

Engine crankcase protection from below- is fixed under the engine and is needed to protect the engine pan on bad road. In principle, if you drive carefully and are not going to move off smooth asphalt, then the probability of hitting a stone with a motor is very small. But if you sometimes move out with ideal smooth road, then engine protection is better to put.

Unfortunately, protection supplied car factory almost always available as an option. plastic and pretty flimsy. Better buy normal steel protection in the store and install her in any car service. The same steel protection will be offered (even imposed) to you by the dealer, as additional equipment, but at the dealer it will cost 3-5 times more than when buying in a store. Decide for yourself what to do, but factory protection usually plastic and weak, but to put additional equipment at the dealer is expensive.

Winter options (heating)

Now oh winter options (heating options). They will be useful to you at negative temperatures.

Especially good when the car is thoroughly frozen. You sit down, start the engine, turn on the heating and after half a minute the seat warms you with its warmth.

Electric heated windshield- a very convenient option in a situation where the car is covered with a layer of frost, snow or ice.

Electric heating thaws windshield literally in a minute, you can go right away without warming up the engine. If you do not have such an option, then you will have to wait 5-10 minutes until the engine warms up and hot air blows onto the glass.

minus electric heating is its high price both when buying a car and when replacing glass. For example, ordinary glass Ford Focus 2 costs 7500 r, and electrically heated glass will cost 10 tr.

Heated side mirrors- This the most important of the winter options. If the heated glass and seats are no longer needed after 10-15 minutes after starting the engine, then the situation is different here.

No matter how hot it is in the cabin, the exterior mirrors will not get warm from this, and driving with frozen mirrors in the city is a direct path to an accident. evaporates moisture, restores visibility and ensures safety in any weather. This function is useful not only in winter, but also in the warm season, such as during rain or fog. - This one of the most important options in automotive equipment.

They are simply necessary for parking in urban areas, when there is not enough space and you have to park back to back.

Parking radar (parktronic) scans the space near the bumper, and sound signal informs the driver about the distance to the obstacle. This allows you to park literally back to back, without risking scratching the car. Along with rear view camera, parking radar is one of the most useful features modern car.

Do not hesitate, if possible, be sure to equip the machine parking sensors. It pays off the first time you park in difficult conditions when will help you avoid damaging your vehicle.

ESP (electronic stabilization system)

ESP- This security option, whose value cannot be overestimated. It's safe to say that it has saved more lives than any other car security system. In the United States, it is illegal to produce cars NOT equipped with this system, although the climate there is much milder than ours and the roads are not so slippery.

For different automakers, this system may be called differently (ESC, ASC, VSC), but the essence of this does not change. We will talk in detail about ESP in a separate article, but in a nutshell we can say that this system is extremely useful on slippery road. It corrects many driver errors and saves the trajectory of movement when the car is without ESP would have been out of the way a long time ago. My to you advice: try to buy a car with ESP. Perhaps this system will save your life more than once.

central locking

central locking, alarm and immobilizer are options that have become so commonplace that it makes no sense to even mention them in the list of options. This kit is now installed even on the cheapest models in the most available trim levels. It can be said that the central lock is last century. Now in trend keyless entry systems when the car itself opens door locks barely catching your approach. In vehicles equipped keyless entry engine starts with button, of course, provided that the key fob is in the car. This modern option is gradually becoming more affordable and can be increasingly found on inexpensive cars.

Vehicle options. conclusions

Summing up, I want to draw your attention to the fact that the more complex systems include car equipment the more likely they are to break. It can be said that full set cars not only raises the price, but also reduces general reliability car.

That's all, dear readers! We wish you good choice of car and generally speaking buy the car of your dreams. Thank you for being with us! Until we meet again, friends.

Vehicles that manufacturers create may have different appearance and inner stuffing. Usually, in the salons they offer a basic package and the buyer himself can choose his own option, based on the resources of the car factory. You do not know which one will be optimal for you, consider the tips below. And it will be easier for you to give preference to one or another type of options.

As a rule, up to 4 different models are offered for each model, including a variety of options. Most often, buyers choose the average configuration, since the basic one rarely meets the wishes of motorists, and the top one is the most expensive.

Every motorist is free to choose. In any salon you will be offered a list of various options, from which you can choose the optimal ratio - comfort. But it should be taken into account that we must not forget about the safety of driving and operation.

Basic (minimum)

The price indicated in specialized, advertising and other offers reflects the minimum options, thanks to which the car moves, but does not have climate control, electric windows, car radio, comfortable mirrors rear view and other necessary components. Even in this form, it can be operated, but this is not enough for comfortable trips.

This applies not only to a “weak” engine, but also to the quality of the discs, the color of the bumper, and good quality you just have to dream. And as a result, you have to pay extra for everything else. In fact, this is a skeleton on which it is necessary to build up muscles and skin.

Medium (classic)

This equipment of the car is standard and it is the most common, since it is possible to upgrade the car, but at the same time. Typically, consumers choose this particular type, which can include (of course, for additional money):


You may be offered a configuration option in a car dealership. But at the same time, you should not rush. The prices of sellers and manufacturers are necessary, since stores add their own trade margins and, as a result, the overpayment for a car can be significant.

Full (luxury)

The most complete equipment includes the use of expensive materials, heaped, expensive spare parts, full set airbags (so-called full stuffing):


Choice engine is coming in several directions: the volume and type of engine (diesel or gasoline). Gasoline engines more popular, they are cheaper, but their resource is lower. Also, the constant rise in price makes them costly to operate.

(can be charged from a special outlet), hybrid - combine two engines: gasoline and electric and gas engines. But such engines require special maintenance.

Safety

Accidents, unfortunately, happen, so you need to take it seriously. Seat belts must be mandatory. Ideally better protection provide airbags. It is possible to choose the most common: frontal, which exist in the form of curtains and additional side ones.

You can order their installation only for the driver's seat (if the car is used by one person). But in this case, seat belts are also required for other seats. For families with kids, you can not do without mounts for. This is the most reliable appearance transportation.

Now let's talk about car safety: it is desirable to have a stabilization system, emergency braking and anti-lock. Little things, but the benefits are more than significant.

Transmission

It all depends on your preferences. Select machine or mechanical box gears. Each has its own advantages and disadvantages. Mechanical ones are much cheaper, break less. But at the same time they require certain skills in driving.

Although for automatic transmission you have to pay a large amount, they are convenient to use. But it should be noted that they have a shorter service life, in the event of a breakdown, they are quite expensive.

An interesting fact is that some deliberately refuse to choose automatic transmission, because they like to control all changes themselves. speed limit. But this is a matter of taste and financial possibilities.

General view (design)

Buying a car, we get not only four wheels and a steering wheel, but also convenience, prestige and beauty. Therefore, the body kit should include chrome parts, they look more presentable.

The same can be said about the bumpers - ordinary plastic black beauty will not add, while those matched to match the body color will add more expressiveness. Separately, it is necessary to talk about paintwork. You can choose a standard paint, but manufacturers offer metallic options, with a pearly sheen, which on the one hand leads to an increase in price, on the other hand, beauty is guaranteed.

Rear view mirrors

IN basic version the cups of the mirrors are usually black or painted in an unattractive dark gray color. Choosing the color of the mirrors to match the tone of the car makes it more harmonious. At the same time, it is worth considering that these parts, after the disks, are most exposed to impacts and chips. This does not mean that you need to abandon the stylish design of the car. It all depends on the occasion and driving style. In a bad scenario, you will have to change both stylish and ordinary mirrors.

Little things without which you will not pass a single police post

The car before the first departure must be equipped in the right way and have:

  1. First aid kit(special designed for these purposes) with a full set of medicines and improvised means. Ideally, let nothing happen on the road, but in the event of a critical situation, it can save the life of the driver and passengers.
  2. Sign emergency stop . Desirable collapsible with reflectors. A breakdown or an accident can happen at any time of the day.

Good afternoon, dear reader.

As you probably remember, in the previous article in the series " How to buy a smart car"The issue was considered, and the final list for purchase was reduced by another 2 positions. Let me remind you that cars that do not suit us at all were excluded from the list.

At the next stage of choosing a car, it is necessary to identify the strengths and weak sides all the remaining models and choose the 2-3 most suitable ones from them. To begin with, I propose to consider possible strengths cars, and in one of the following articles I will tell you in detail about the possible disadvantages.

So, today will be considered selection of equipment specific vehicle and possible installation options.

What are the packages and options?

To begin with, I want to explain the difference between the concepts of "complete set" and "option", so that in the future you will not have any questions about this.

So equipment is a car that already has a certain set of options installed. Usually specific model The car has 3-4 different configurations.

The simplest equipment is usually called basic and contains the least number of options. Accordingly, the price of such a car is the lowest.

The most sophisticated equipment is called the top. It has the most options. The same can be said about the cost.

In practice, most often they buy cars of medium configurations.

Note: Each automaker chooses its own trim names. You can determine the basic, medium and top configurations yourself, focusing on their prices.

It is worth noting that some options may strictly correspond to the configuration of the car. For example, depending on the equipment, only a certain type of interior upholstery can be installed in a car. Also, very often, the type of car engine is rigidly connected with the configurations. Most powerful engine for the selected model, in most cases, it is installed only in the top configuration. For other configurations, it will not be possible to get it.

Option or option package - optional equipment which can be installed on the car. All can be included here additional device, which were not included in the basic package, but can be installed on the car for an additional fee.

For example, as options are often offered fog lights, air conditioners, security systems and other structural elements.

Do not forget that certain options can only be installed on certain configurations of the corresponding car.

For example, fog lights and power steering may be optional on the base trim, but are included by default on the mid trim. Those. you won't have to pay.

Second example. can only be installed on cars of medium and top trim levels. In this case, even with his great desire, the driver will not be able to get ABS system for the base car.

Third example. In the basic and medium configuration of the car, air conditioning is offered as an option, and in the top - climate control.

I hope you understand everything. The only conclusion that can be drawn here is Not every option is suitable for a certain vehicle configuration.

In addition to all of the above, one should distinguish between factory options and interior options. Factory option- this is an additional equipment that is installed in the car body at the factory. Usually the options installed at the factory are of the same quality as the car itself.

Salon option- additional equipment installed in the dealer's salon. Typically, alarms, music systems, parking sensors, etc. are considered as interior options. The quality of these options depends solely on the skills and abilities of the installer. Quite often, it is practiced in dealerships that the same person installs all electronics (alarms, parking sensors, music), respectively, he can install only 1-2 models of car radios, 1-2 alarms, etc. Those. selection may be sparse, and installation quality may lag behind vehicle build quality.

If you have to choose between factory options and saloon options, then I would recommend choosing factory options.

This concludes the theoretical part of the article, and I will move on to considering specific options and their need for a particular driver. I note that only the most common options will be considered below. This is due to the fact that some automakers can come up with their own options and a dozen articles are not enough to consider each of them.

Selection of a complete set of the car. Select the required options.

Engine type and size

engine's type depends on the type of fuel used. There are 2 types of engines - gasoline and diesel. It should be noted that diesel fuel is currently cheaper than gasoline. Also, cars with diesel engines in most cases have a higher. I note that at present in Russia it is extremely difficult to find a car worth up to 500 thousand rubles, which would work on diesel fuel. Vehicles with diesel engine usually cost more.

From engine size first of all depends on its power. Generally, the larger the volume, the more power. However, the relationship between these quantities is indirect.

A more powerful engine allows the car to reach 60 km / h faster than others. The same applies to country roads. The more power, the faster car reaches a speed of 90 km/h. However, after that, it will not have any advantage over a car with a smaller engine.

It is impossible to ignore the fact that cars with a large engine capacity tend to consume more fuel, so trips to them turn out to be somewhat more expensive. In addition, the size transport tax, charged from car owners annually, directly depends on the engine size.

The most common types of engines were considered above. However, in addition to them, there may be electric motors(the car is charged from the outlet), gas engines (they use natural gas), and hybrid engines(using several types of fuel at the same time).

Since such engines are not widely distributed in Russia, I will not focus on their features.

Security options

You can get detailed information about possible security options from the "" series of articles. Here I will briefly dwell on each of the options.

Seat belts- simple safety features that are nevertheless very important. It is highly desirable that all passenger seats vehicles were equipped with three-point inertial belts security. In addition, it is desirable that the driver and passenger belts have pretensioners and force limiters.

A nice and useful addition would be the height adjustment of the belts, as well as the mount for a child seat.

Airbags. About airbags, it should be said that the more of these same pillows, the better.

Typically, cars are equipped with the following types of airbags:

1. driver front airbag;

2. front airbags for the driver and front passenger;

3. front airbags for the driver and front passenger + side airbags for the driver and front passenger;

4. front airbags for the driver and front passenger + side curtain airbags for the entire cabin;

5. front airbags for the driver and front passenger + side airbags for the driver and front passenger + side curtain airbags for the entire cabin;

In addition to these kits, automakers often come up with their own types of airbags. For example, to protect the driver's knees. Once again I emphasize that the more pillows in the configuration, the better.

Electronic driver assistance systems. Such systems include an emergency braking assistance system, as well as many other various electronic systems.

In my opinion, it is not worth saving on security systems, so the more of them, the better. I will only note that these systems will not harm the driver in any way, because. they work fully automatically.

Vehicle appearance

Painting elements of the car body. Depending on the configuration of the car and on the options chosen, it may or may not have bumpers, rear-view mirrors, door handles, side moldings painted in body color. Whether it's good or bad, it's up to you to decide. I will only note that on the painted elements of the body there is dirt and small scratches can be seen much better.

17.08.2012

For every new car without fail applied service book, manufacturer's instructions for the operation of the car, list necessary tool and accessories, two sets of keys, which include the key for the ignition lock and the key for the driver's door and trunk lid.

The car that passed pre-sale preparation, must be clean, serviceable, fully charged with oil, coolant and brake fluids. The level and density of the electrolyte in battery must also comply with the requirements set out in the manufacturer's instructions.

Traces of conservation grease on chrome parts, small dents and scratches on the body, cracks on the glass lighting fixtures or mechanical damage to the tires of the wheels are not allowed.

When buying a car, it is useful to bend down and look at the area under the car with the engine running. There should be no traces of oil, liquids, fuel leaks on the floor.

When inspecting a used car Special attention you should pay attention to the condition of the body, the cost of which exceeds half the cost of the entire car, carefully examine the color of the body. Hidden body defects are easily detected by gloss, color, stains or touch-up spots. If the clean washed surface of the body is matte, then the car has served for more than 2 years, since the color of the enamel changes over time. Separate shiny spots found on such a body indicate a recent touch-up of the car. Under these surfaces, there may be signs of an accident or corrosion due to careless maintenance of the vehicle. Detected bulges of the body metal, traces of old paint under the sealing gaskets of the windshield or rear window testify to the repair and repainting of the car.

Damage to the body, especially in an accident, can be significant, which often leads to a violation of vehicle controllability. This can be easily identified by the installation of the front wheels and their external state. If both front wheels are turned inward or outward, then this indicates, respectively, too much or too little convergence. And if there is a turn of the front wheels to the sides in a vertical plane, then this is a broken camber, which is a characteristic sign of a past accident.

During an external examination of the car body, it is recommended to check the reliability of fastening the hood, the tightness of the fit of the trunk lid and doors, the ease of opening and closing them, and the reliability of the door locks. It is necessary to pay attention to the glass frames, to fixing the glasses in a given position, to the door hinges.

When the locks are in good condition, the hood, trunk lid, doors should open and close easily, without much effort, have a uniform clearance along the perimeter with the body. Traces of rust on the door and trunk hinges, moisture on the interior upholstery, smudges in bottom corners With inside glass frames, on decorative strips or at the bottom of the doors indicate a violation of the tightness of the body due to aging or mechanical damage seals for trunk openings, doors and other seals.

When inspecting the interior, it is necessary to pay attention to the condition of the upholstery, rubber mats, pads on the pedals, trim on the seats, on the reliability of the fastening of the seat, on the operation of the mechanism for adjusting and tilting the seatback.

Tears and stains on the upholstery, a dented driver's seat are characteristic features used car, and the availability small cracks on the steering wheel indicates that the car has been in a traffic accident, since the plastic on the steering wheel usually cracks with a strong impact.

The mechanisms for longitudinal movement and inclination of the backrests of the driver's and front passenger's seats must operate smoothly, without jamming and not have large backlashes. When inspecting the interior, it is imperative to check the condition of the steering, test the operation of the control pedal throttle valve carburetor, clutch pedals, brakes, gear lever, power window operation.
