Second-hand car identification method how to eliminate the accident car?
Many of the friends who have passed the driving license are eager to buy a car to practice their hands, but if they buy a new car, the driver’s limited skills will be very frustrating if they appear, but it’s best to use a used car to practice. But in the process of buying a used car, how do you identify it? Let's listen to an expert introduction. 1. First, observe the appearance. If it is an accident car, it must be completely refurbished before it can be sold. However, there will always be clues, you can observe whether the gap in the middle of the body is symmetrical, whether the lines on the waist of the vehicle are natural, and it is difficult to consider these two points even if the accident vehicle is renovated. If you think it is difficult, you may wish to observe the glass of the car and check whether the glass age is in line with the year of delivery of the car, because the glass of the accident car will be completely replaced. 2. Observe the door condition of the vehicle. If it is an accident car, the door must be damaged. Even if the door is repaired, it will be difficult to observe whether the seal is intact. And after touching the sealing strip, the lines of the door frame and the post should be parallel. The place where there are solder joints on the door frame should also be round and slightly concave. In addition, if the three pillars of the vehicle paint are very large in color, it can be fully explained that this vehicle is an accident vehicle. 3, you can also observe the presence of abnormalities in the front cover, be sure to carefully observe the side of the corner, such as the firewall is normal, whether there are signs on both sides of the fender repaired. The tank frame is also a part that needs to be observed. Check that the screws are intact and have not been screwed through. In addition, the trunk should be inspected. Whether there is any sign of re-welding at the joint between the shock absorber and the fenders can be checked. Finally, the car chassis can be inspected to see if there are any traces of overhaul. If there is something wrong with these parts, it must be an accident car! After the above introduction, I believe that everyone has a deeper understanding of whether or not a used car is an accident car. When you purchase a used car, you must carefully observe it carefully. As long as it is an accident car, it will always show flaws.
