Is it better to replace or repair the car with deformed parts?

From the maintenance method, we can see that the method of cutting and welding hurts the car, and after welding, it is no longer an overall structure with the original car, and the strength of the body must be reduced. So if these places are injured, if the deformation is slight, even if it is the responsibility of the other party, the other party pays, try not to replace it, plastic spray painting is fine. If the deformation area is relatively large, the depth is relatively deep, or it is technically irreparable, it must be replaced. Because the deformation is too large, even if it is shaped, because the metal has been bent once, the strength here will also decrease, which may not be as good as replacement.

Parts that can be replaced separately are not harmful to the car, and can be replaced regardless of the size of the damage. But the premise is to replace the original parts, and the quality of the sub-parts cannot be guaranteed. So if it is insurance or the responsibility of the other party, go to the 4S store to repair the car, at least the original parts here. Strictly speaking, damaged parts that can be replaced separately are not considered accident cars, because the safety and other performance of the car are not affected. Only damaged parts that cannot be replaced separately are considered accident cars, regardless of the size of the damage.
