See/listen/use/search detailed solutions for second-hand car purchase

First, in the "look" to work hard This "see" word can be a lot of it, we must first look from outside: first look at the color of each part is the same, the window around the exhaust pipe and other corners are not easy to observe there is no excess paint, If you have this car, it may be a refurbished car. Look at the edge of the headlights and the edge of the rear taillights for any impact marks, because the car can easily hit this area. Then open the hood and trunk one by one to see if there is any paint repair or overpainted area, if any, then the vehicle has been repainted. In fact, as long as the vehicle has not undergone a major collision, repairing the small scraper will not affect the safety. If a large collision occurs, the vehicle body will be deformed and the rigidity will be deteriorated, which will directly affect the safety. In addition, body deformation and suspension deformation will affect the stability and comfort of driving, and thus affect safety. For these deformations of the body and suspension, the average person is usually invisible. It is best to find a friend with maintenance experience to look at the car with you and test drive together.
In addition, check the tires to see if the tires are worn out. If they are uneven (heavily worn on both sides or in the middle), it is very likely that the suspension of this vehicle needs to be adjusted and four-wheeled or even needs to be repaired.
Second, in the "listen" to work hard to knock on the body, if the sound is crisp, it is normal, if the sound is boring, this car may make up putty. Then start the car and hear the sound of the engine, whether it is even, whether there is a knocking sound or a buzzing sound, whether the jitter is serious and so on. Also in-situ refueling, feel the sound of the engine changes evenly, while maintaining the throttle in different positions, to see if the engine speed is stable.
Third, in the "use" efforts Regardless of whether to buy a new car or a used car, you need to test drive in person to make a conclusion. Pay attention to whether the indicator light of the instrument is in good condition before driving, and whether the position of the steering wheel and the seat is comfortable. When the car is running, it is necessary to test whether the brakes have problems and whether the steering wheel is aligned. In addition, on the flat road, you should feel whether the body is moving or whether it is running. During the test drive process, we must also choose bumpy roads to feel the chassis system, especially whether the suspension has any abnormal noise when crossing the ditch, and whether the vibration of the body is even. You can also use the linear acceleration to feel the throttle response speed, and whether the acceleration is smooth.
Fourth, the "check" efforts are mainly to check procedures. Whether the source of the used car is legal and whether the formalities are true and complete, especially when the owner of the car purchases directly. If you can't confirm it, then the owner must go through the formalities with you to the used car dealership to avoid unnecessary losses.
