The check of the air intake grille is part of the appearance inspection of a used car, which is a relatively obvious part of the car, but it also requires the carefulness and patience of the consumers to see the problem. Under normal circumstances, a new car that has just been shipped, or a used car that has not had an accident, should be very neat in appearance. Therefore, when we check the vehicle, we can check whether the screws fixing the air intake grill are passive to judge whether it has changed the air intake grill due to an accident. On the other hand, many of the intake grills are of hard plastic structure. If there are used cars for several years, their intake grilles will suffer from chromatic aberration or dirty surfaces after they are subjected to high temperatures. These are normal. However, if you open the front cover of the machine and find other places are dirty, and the grille is very clean, then the car is likely to have been replaced and replaced the grille.
  
Xiao Bian reminds consumers that some of the cars that have been hit but did not injure the internal skeleton structure of the car body are used by regular dealers. It is important to pay attention at this time. The common rule is usually to adjust the air grille or replace it, so that it looks as if no accident occurred. However, there are always some traces that are less symmetrical than those that have been replaced or adjusted. Therefore, Xiao Bian strongly recommends that we pay high attention to this important part when selecting used cars.
  
The position of the intake grille on the front face is generally relatively large, and it is also a site where the collision is easily damaged. Everybody inspects the appearance of this part carefully and seriously. Although the replacement of the intake grille does not affect the use of the vehicle, it is an important reference for the accident of the vehicle. In order to ensure that you can pick a reliable used car, the inspection of the air intake grill can not be ignored.
