When buying a used car, what do consumers value most? In addition to the mass of choices, at affordable prices, car quality is their most concerned issue. Different from the new car, each car of the used car will be different due to the vehicle condition, maintenance condition, and wear condition. They are all separate products and it is difficult to have a uniform standard. How to test a used car and evaluate the value of a used car? As a consumer, understand some of the used car detection knowledge, to help make their own judgment when buying a used car. The senior inspector Baishun of Youxin used car introduced us to the following basic steps. The first step in testing a used car is the vehicle's various documents. It is the basis for the identification of a used car, only with complete formal documents, this used car can participate in transactions. Now, various documents can be verified on the official website of the traffic police to identify authenticity. The two important numbers involved in the certificate: the body number and the engine number must be exactly matched. The body numbers of different brand cars are different, but they are all in a prominent position. The "detection" of these parts can be said to be the key. Figure: Identifying car identification numbers is the first step in testing Formal inspection of the body begins with appearance. The basic judgment is to see if the car has scratches and there are no depressions. Professional surveyors recommend a 45-degree observation method - standing at the front and rear of the vehicle, a total of four positions, and observing the appearance of the vehicle at a 45-degree angle. This observation not only makes it easier to see if the car has scratches, but also finds hidden depressions that are not visible when looking directly. When light is abundant, such observations are quick and effective. Figure: Visual inspection The most important part - the chassis and the keel. Observe the bottom of the vehicle and the professional machine is needed to lift the car. The tester can see a lot of chassis by leaning down slightly. By observing the position of the engine at the bottom of the head, it can be seen whether or not the vehicle is leaking oil. Looking at the dragon's skeleton position can determine if the car has a major accident. The appearance of the car, even the depression, is difficult to see after it has been repainted. However, if there are depressions and offsets in the keel, it is necessary to change the entire vehicle skeleton. By observing the integrity of the skeleton itself and the interface with the car, the accident record of the car can be clearly understood.

Sit into the car, start the car and check all switches. When the switch in the car is checked, the flame is turned off, and then the car key is hit in the second gear, and all the lights in the instrument cabin are normal. When checking the gear, check the engine startup status. If a certain number of gear shifts cause the car to be strongly frustrated, there are certain problems. After the car was inspected, the engine was tested at the last step. The engine needs to be checked with a very professional instrument, but the examiner also has his own skills - listening by ear. Keeping the engine starting, under normal conditions, the sound of the engine is smooth and low. If the engine is loud and there are sharp, irregular noises, this is a problem.

Youxin used car has a powerful and complete testing process to protect the consumer's car purchase process. “Every dealer’s car is able to enter information on Youxin’s used car through the tester who has many years of experience, from the document record and appearance to the detailed inspection of each part, which is presented to consumers.
