It is normal that the deformation of the spare tire groove does not hurt the girder, which is a big accident. The following is an introduction about the accident car: 1. Definition: A car whose anti-collision beam has been repaired or replaced is not an accident car. If the damage of these parts causes serious damage to the performance of the car, it can be considered as an accident car, otherwise it is not an accident car. 2. Judgment of the accident car: From the front, when the front bumper of the car collides head-on, the front bumper will deform and squeeze the collision beam, and then the energy of the subsequent water pressure tank will squeeze the engine. Generally speaking, when you turn on the engine, you can see the fan and water tank of the car. If there are signs of replacement, it means there is a problem, then continue to look at the girders on both sides of the water tank. A fixed anti-collision beam extends from the girder, and if it hits from the front, it will be deformed, even if it is repaired by sheet metal, it will not return to a flat appearance, just as paper will not be flat after bending. In terms of impact, the front impact beam bears a lot of force. The back is where you can see the spare tire when you open the trunk. That place can't be replaced, it can only be remodeled, so it's easier to see if there is anything wrong here. Some cars have no rear bumper, so the rear of the car body is fragile.
