whether it is an accident car or not depends on how the tailgate is repaired. If it has been cut and replaced, it is an accident car. If you just knock, knock and pull on the bench, this kind of repair without cutting or welding is not an accident car. In fact, in most cases, the repair of the backboard needs cutting and welding. In rare cases, sheet metal repair. As long as the car has been repaired by plastic surgery, cutting and welding, it is an accident car. If it is an accident car, the strength will drop a lot after it is repaired, and it will depreciate a lot when it comes back to sell used cars. Although sheet metal repair is not an accident car, it has little effect on selling cars in the later period, but it should be analyzed according to the actual situation. If the damage is serious, it must be cut and repaired. Because safety comes first. After the introduction of vehicle depreciation: the loss of vehicle depreciation refers to the loss caused by the damage of vehicles in traffic accidents. Although the service performance of the vehicle has been restored after repair, it is difficult to restore the service life, safety performance and handling performance of the vehicle to the previous state, and the actual value will inevitably decrease, that is, the loss caused by the decrease of the vehicle value caused by the accident.
