Under normal circumstances, if the 4S shop is required to assemble the original bumper, then the 4S shop usually must use the original parts.

1, the advantage of the original bumper lies in its toughness, which is difficult to deform even under high-strength pressure. Secondly, because it is directly supplied by the original factory, there is naturally a better guarantee in quality.

2. Bumpers are lascivious when they leave the factory. However, it is not excluded that some 4S stores get goods in the branch factory for profit, and these bumpers are basically painted in the later stage of 4S stores. Naturally, it is not as stable as the original assembly line, and there will even be some color difference.

So after replacing the bumper, be sure to check the logo or original label on it. If it is not the original factory, you can negotiate with the 4S shop.
