The used car market has become more and more popular in recent years. Some people found satisfactory cars in the used car market, while others complained that they had been cheated more than once. It is undeniable that in the eyes of ordinary people, the market for used cars is really "deep", but as buyers, there is no way to know some basic "doorways" of used cars in advance, or you can take fewer detours and suffer less.

I. Basic "software" inspection

1, considering vehicle age.

1-3 years old used car is the best; 3-5 years old used cars have the highest cost performance; Used cars over 8 years old need special attention.

In the used car market, there are often vehicles that have been used for two years or even months. This kind of used car is in good condition, and you can continue to enjoy the manufacturer's warranty period after purchase. However, the number of such vehicles is small and it is easy to be tampered with by used car manufacturers. The price of used cars for 3 to 5 years is relatively high, so it is also a good idea to buy used cars with appropriate cost performance. Used cars that are 5 to 8 years old are cheaper, but you must buy them carefully. They may already be a few cars, and there must be many problems in their condition, which need special attention.

2. Mileage is very important

The service life of a car is determined by the service time and mileage. After the average vehicle travels1.5,000-0.2,000/200,000 km, the technical performance of the vehicle drops obviously and the repair cost increases. Generally, the mileage of used cars can be read directly from the odometer, but now more and more mileage is changed by used car dealers. In this case, you must be careful and find another place to test yourself if necessary.

3. Road test is essential.

Many people who buy used cars read the basic summary, listened to the introduction of second-hand shops, and bought them rashly without driving on the road. In fact, the road test can fully understand the handling, stability, braking performance, clutch and dynamic performance of used cars.

Second, the "hardware" check

The so-called hardware inspection is to check whether all kinds of auxiliary equipment of the vehicle are working normally, such as wiper, reflector, hygrometer, heater, defroster, lamps, turn signals, air conditioning equipment and so on. Then focus on the following:

1, car paint

Observe whether there are traces of repainting after the paint falls off, and check whether there is excess paint around the exhaust pipe, molded parts and windows. If the vehicle is refurbished, it can be used as a reference for old and new vehicles.

2, the degree of physical damage

Observe the joints of the car body. If the seams are not straight, the gaps are different in size, the lines are bent, and the decorative strips fall off, it proves that the car has an accident and has been renovated or overhauled.

3, the body corrosion degree

Mainly check the protective plate, window, sink, bottom plate and joint for corrosion. If the corrosion is serious, it proves that the car is old.

4. Shock absorber and suspension system.

Press the corner hard. After relaxing, the car should be able to bounce back and jump freely two or three times. Otherwise, it is proved that the shock absorber or suspension system spring is not working well.

5. Front wheel alignment

Jack up the front wheel and swing it up and down by hand. If there is a gap, the bearing and ball head are worn. Observe whether the front wheel wear is uneven and whether there are cracks on both sides. If the eccentric wear is serious, it proves that the front wheel positioning is incorrect.

6. Steering situation

Park the vehicle on the flat ground, turn the steering wheel, and check whether the steering free stroke is too large and whether the steering rod and ball head are loose.
