The first thing to look at is the appearance of the car, such as the smoothness of the paint surface, whether there are scratches on the paint surface, whether the paint surface has been repainted, whether it has been refurbished and so on. These are my first impressions of cars.

Second, look at the internal structure of the car body, such as whether there are traces of impact, the degree of internal corrosion, and whether the car body is deformed. The main purpose is to know whether the car is comfortable to drive and how long it will last.

Third, look at the chassis structure, such as the size of the operating gap of the steering system, whether the brake system leaks oil, and whether the structural parts of the suspension system are loose. This is mainly to know whether it is safe to use it immediately.

Fourth, look at the engine, such as whether there is oil pollution on the engine body. Let the engine start here, and listen to whether the sound of the engine running is low, and whether the engine reacts lightly when stepping on the throttle and releasing the throttle. See if there is blue smoke and white smoke in the engine exhaust. Whether the engine is stable when working. These are all to understand the working condition of the engine.

Fifth, it is a trial run. The main understandings during the trial operation are:

First, whether the operation buttons are perfect and the configuration in the car is complete.

Second, the operation feeling is mainly whether the direction operation is flexible, whether the gear position is clear, whether the clutch is smooth and whether the brake is accurate.

Third, the riding experience is mainly comfort, such as whether there is noise in the car when starting, whether there is noise in the floor when driving, etc.

Sixth, verify that the car's documents are complete. Understand the service life and mileage of the car. Psychological evaluation of the car, if it is not much different from the price of others, the possibility of a deal.

Finally, there are legal transfer procedures in the office. These transfer procedures are handled at the vehicle management office, and the ownership of the car. You can go through the formalities yourself, or you can entrust others to handle it (generally, the operators of the used car market also handle the transfer procedures for customers with compensation).

After the transfer formalities are completed, the car will really belong to you.

Besides, this is also very good.

Avoid the appearance defects and quality problems that exist when leaving the factory, prevent the car from being damaged due to inventory backlog and transportation, and prevent the old car from being rebuilt and refurbished.

The inspection should be carried out in a well-lit place, so that you can see clearly. From the factory to the customer's hands, the vehicle has experienced many links such as transportation, storage, open-air placement, and even sun and rain. In particular, imported cars need to go through land transportation, sea transportation, customs warehouse and other links from the production workshop to the seller, which takes a long time, so be sure to look carefully when buying.

Some cars have technical problems in the manufacturing process, and even some dealers steal columns and renovate old cars to deceive customers. Therefore, when buying a car, you must polish your eyes to prevent leaks.

1, appearance

(1) If you look at the car paint carefully, if you find that the color or thickness of a certain part of the paint surface is inconsistent with the surrounding area, or there are tiny circular scratches, it is mostly caused by repainting after damage.

(2) Check whether the clearance between the front cover, the door and the surrounding frame is even, and whether there is a big difference or a small difference. Open the door as flexibly as possible. Don't open the door too hard, and there should be no noise on the door shaft. Whether the door can be closed in one step, the sound heard when the good car closes is dull, the strength difference is small, the door is not closed tightly, it needs a strong impact to close it, and the sound is sharp and unpleasant.

(3) Carefully check the vehicle accessories, such as batteries, wipers, tires, engine oil and other consumables to see if they are aging.

(4) Check the working conditions of chassis, wheel arch, shock absorber and suspension. You can press the corner of the car body hard by hand, and then look at the number of bounces after releasing it, preferably between 2-3 times.

(5) Check whether there are any repair marks on the engine room and the bottom edge of the car, in case of buying an accident refurbished car. When checking the chassis, you can drive the car into the ditch to facilitate the inspection.

(6) Observe the appearance of the whole vehicle at a distance from the vehicle and browse carefully. For example, whether the height of the car body is symmetrical, whether the windshield is intact, and whether the tires are intact and wear-free.

2. In the car:

(1) The door glass should rise and fall freely, and the sliding window switch should be easy, smooth and well sealed.

(2) All instruments on the dashboard should be complete and effective, not reflective, and not blocked by any objects. Pictograms can be accurately understood and easily identified.

(3) Shake the steering wheel by hand. There should be no gap between up and down, and the left and right free travel should not be too large, so the surface feels good.

(4) The seat surface should be clean and intact, without damage or scratches. The front seat can move back and forth freely, and several positions can be fixed, which is convenient for passengers to choose the right seat freely.

(5)

After sitting down, put your hand on the steering wheel and step on the clutch pedal with your left foot, you should feel relaxed and have a short free stroke; Keep a certain height when stepping on the brake pedal with your right foot. If the downward movement is slow, it indicates the braking system.

There is leakage; The accelerator pedal should not be stuck, heavy and not return. Put your legs and feet on the accelerator pedal and be comfortable naturally, so as to ensure that you are not tired after long-distance driving.

(6) The softened doors and automobile interior trim panels should be clamped in place and should not be loosened when pushed down by hand.

(7) Open the engine cover, and first check whether the water tank replenishment fluid, cleaning fluid, power steering fluid, lubricating oil and brake fluid are normal. If it is not normal, a leak should be suspected. The appearance of the liquid tank should be clean, free of water marks and oil stains, and the liquid level can be regarded as normal between the highest and lowest scales. The connection between the battery fixing pile head and the electric wire should be reliable and good, and there is no looseness by manual pull.

Check new car program

Buying a car now is mostly a one-stop service. However, you should personally participate in the car purchase process as much as possible, and be aware of it. Don't save trouble, leave everything to the dealer.

( 1)。

Check whether the car is consistent with its nameplate: engine number, frame number, product certificate and factory date, all of which are the characteristics that indicate a car's "legal identity". The number on the certificate should be the same as the engine number and frame number of the car.

Consistent. Judging whether it is a backlog car from the factory date, and knowing the time from production to sales. In addition, models, power, number of seats, engines, etc. Requirements are consistent with the real thing. If there is a discrepancy, it will not only cost you money.

It is a waste of money, and it is impossible to go through the formalities of car inspection and licensing in the future.

(2)。 Check the import documents: when buying imported cars, you should carefully check the import goods certificate and the tax bills such as customs duties and value-added tax payable. Otherwise, you will buy an imported car with incomplete procedures. First, the quality cannot be guaranteed. Second, you will not get a license plate because of incomplete import procedures when you apply for a license plate.

4. Test run to understand performance

After the static test is completed, you should further understand the performance of the vehicle and experience it in your own test drive. During the test drive, check the ignition, starting, shifting, acceleration, turning, foot braking, hand braking and the use of vehicle lighting to understand whether the vehicle is running smoothly, quietly and comfortably.

(1) Start the engine, and listen to the speed, including whether the engine starts quickly, whether it runs briskly, continuously and smoothly, and whether there is noise or abnormal sound. Get back in the car, lightly step on the accelerator and feel whether the acceleration response of the engine is continuous. After continuous acceleration, the idle speed should remain stable.

(2)

Fill the throttle slowly and lift the clutch lightly, and the vehicle should be able to start smoothly. The shift of a new car may not be smooth, but it should not be stuck, hung or taken off, and it should not be blocked. Lightly step on the brake at low speed to test the braking strength and braking response.

It should be good. You can also try to slide in neutral, such as driving at a speed of 20km/h, and sliding on a flat road can be 50 ~ 80 meters. If the car stops quickly as soon as it is in gear, it means that the moving parts are installed, debugged and lubricated.

Improper sliding, such as bearing tightening, brake scraping or lubricating oil solidification.

(3) During the trial operation, the overpass can feel acceleration and power; Feel whether the steering system is satisfied by shifting gears up and down and tapping the steering wheel; During normal driving, the direction should not deviate, and it can automatically keep driving in a straight line, and basically return to the right side after turning (90%); When the vehicle turns left and right to the extreme limit, the wheels should have no abnormal sound.

(4)

If possible, you can try to drive at high speed, feel the stability and grip of high-speed driving, and see if there is wheel swing and direction drift. When there are no other vehicles, you can also try to snake and feel the handling of the vehicle.

Yes; You can also test the feeling of emergency braking at different speeds, such as braking at 40km/h, 60km/h and 80km/h respectively, and check the directional stability during braking.

If you lack confidence in the trial operation, you'd better ask an experienced friend to help you check, and the problems found on the spot can be handled in time. If something is wrong in the future, I'm afraid I can't tell whose responsibility it is.
