The technical condition of the used car is directly related to the time of use of the vehicle. The current performance of the car can be preliminarily estimated by looking at the time at which the used car is manufactured. Generally, the used car's delivery time can be found by the owner or by checking the vehicle data. However, due to the fact that imported cars cannot be determined due to their use and residence time abroad, this method can only be understood. The most accurate method is to look up from the technical data of the vehicle. Most of the time for importing a car is not directly marked on the vehicle's nameplate. Instead, only the frame number is used instead. Check when checking.
The service life of a car is determined by the time of use and mileage. After a typical car has traveled between 150,000 and 200,000 kilometers, the technical performance of the vehicle has been significantly reduced, and the cost of repairs has increased. The mileage of a used car can generally be read directly from the odometer. The mileage of some imported cars is calculated in miles. Attention should be paid when searching. Some used car odometers are replaced or malfunctioned. At this time, they can only be estimated based on the time of use of the car and the frequency of car use by the owner. It can also be estimated by observing the degree of wear of the tire. There is a gap between this estimate and reality and it can only be used as a reference. The less mileage a car has, the greater the reserve mileage.
When purchasing a used car, first of all make sure that the vehicle's various ancillary equipment is working properly, such as wipers, mirrors, humidity meters, heaters, defrosters, lamps, turn signals, and air conditioning equipment. Then focus on the following items: First, car paint. Observe whether there is any trace of heavy spray after the paint is peeled off, and check if there is any excess paint around the exhaust pipe, moldings, and windows. If the vehicle is refurbished, it can be used as a reference for the old and new vehicles. The second is the degree of body damage. Observing the joints of the car body, if the joints are not straight, the gaps are of different sizes, the lines are bent, and the decorative strips are peeled off, which proves that the car has had an accident, and has undergone overhaul or overhaul.
Then there is the degree of body corrosion. Mainly inspect the protective plate, windows, sink, floor, and whether or not there is any rust in the joints. If the corrosion is serious, it proves that the car is older. Fourth, shock absorbers and suspension systems. The editorial suggestion is to force down the corner of the car. After relaxing, the vehicle should be able to bounce back and beat freely two or three times. Otherwise it proves that the shock absorber or suspension spring is not working properly. Fifth, the front wheel positioning situation. Use the jack to lift the front wheel and use the left and right hand to swing the front wheel up and down. If there is a gap, the bearing and the 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, prove that the front wheel is not positioned correctly. Sixth is the turning situation. Park the vehicle on a flat surface, turn the wheel back and turn the steering wheel to check if the steering free travel is too large and see if the steering rod and the ball head are loose. Then there is a test drive on the train to check the quality of the car through driving experience.
Through these four methods of checking used cars, I believe that many riders know how to effectively evaluate used cars. Of course, these assessment techniques are just literal. In fact, any experience needs to be understood through actual operations.
