With the change of people's consumption concept, used cars are becoming more and more popular, but the problems of used cars are difficult to find easily. Therefore, buying used cars requires not only certain knowledge, but also certain skills and methods.
First look at what is the value of the used car. The value of the used car is the equipment residual value people often say. The commonly used calculation method is the “54321 methodâ€. Specifically, if a car’s useful life is 300,000 kilometers, divide it into points. It is 5 segments of 60,000 kilometers each. The value of each segment is 5/15, 4/15, 3/15, 2/15, 1/15 of the new car price. Assuming that the new car price is 100,000 yuan and it has traveled 120,000 kilometers, the value of the car is roughly: 10 x (3 + 2 + 1) ÷ 15 = 4 million.
Mastering this formula can help you to understand the price of a used car in general, but the value of used cars of different types, different grades, different manufacturers, and even different colors is different, and some differences are still quite large, so be sure to Do your homework before buying and check the average transaction price of the car you want to buy. In addition, the price of a car is inextricably linked with its specific vehicle condition. Therefore, besides looking for a knowledgeable friend, you have to master some techniques to identify the condition of the car. The following Xiaobian will introduce you to the following 5 Kinds of skills for buying used cars.
First, it depends on the appearance and operation of the engine. The engine is the "heart" of the vehicle. The condition of the vehicle mostly refers to the condition of the engine, namely the wear of the cylinder liner, the piston and the piston ring. In general, the engine with good vehicle condition is easy to start, the idle operation is stable, and there is no irregular vibration; there is no oil leakage, water leakage, or air leakage at the oil pan, cylinder gasket, spark plug, etc. If the discharged exhaust gas is black, it means the carburetor. There are problems with the high-voltage circuit and the combustion system; the discharged exhaust gas is blue, indicating that the piston ring is seriously worn out and the oil is trapped in the combustion chamber.
Second, to see the extent of tire wear. The service life of the vehicle is proportional to the mileage. The less the mileage, the better the vehicle condition. However, most people selling old cars will adjust the odometer to a limited number to indicate that the car is in good condition. For a tire of 300 to 500 yuan, the original owner will not spend a lot of money to update. Therefore, looking at the odometer plus tire wear can roughly determine the overall condition of the used car.
Third, to experience the driving performance of the vehicle. The most direct experience in judging the condition of a used car is the smoothness of the vehicle. During the test run, after driving for a period of time until the engine temperature is normal, listen carefully to the sound of the engine is stable, and then frequently shift gears to see if the vehicle's response is smooth during acceleration and deceleration, and whether the gearbox synchronizer is flexible. Temporarily loosen the steering wheel on a wide surface to see if the car will run off. If you are in the test, once the abnormal vibration of the high-speed vehicle, especially the steering wheel jitter, indicates that the car has serious problems, you should try another one.
Fourth, to find the traces of the accident. Some used cars were shot after a major accident. In general, vehicle accidents are performed in the front of the car, while the front is where the key parts such as the engine are located. Therefore, it is necessary to carefully look for the situation at the front. You can observe whether the girders of the chassis are symmetrical, whether the electronic fan and the screws in the water tank are reopened, and whether the windshield rubber seals have been reinstalled. In general, it is best not to buy accident vehicles, and the accident traces at the rear of the vehicle have little effect on use.
Fifth, to check the body condition. Can not be confused by the appearance of the car, to be more patiently turn around the body a few laps, carefully observe the mudguard and the lower edge of the door rust situation. In general, the plates in these areas began to rust in the fourth year of use. The more severe the corrosion, the longer the service life.
