The appraisal standard of major accidents of used cars is that any main structure (non-detachable part) including top side beam, bottom side beam, rear fender, rear trunk and side wall has serious sheet metal repair or even cutting, splicing and welding.

The state has a strict definition of accident car, and there are clear regulations on the discrimination of accident car. The biggest difference between an accident car and a major accident car lies in the degree of damage. Any vehicle with structural damage, deformation or fracture of the body frame must be an accident vehicle. If the body frame is not damaged, but the fender, door panel and other parts are repaired by sheet metal painting, it is not a major accident car.

extent of damage

In the second-hand car market, an accident car refers to a vehicle that is damaged by an accident due to unnatural wear and tear, resulting in a decline in mechanical performance and economic value. Major accident vehicles generally refer to vehicles with structural damage. Because the structural parts themselves are integrated, as long as they are damaged, they must be cut and welded to repair, and the safety will be greatly reduced. Therefore, any vehicle with damaged structural components will be characterized as a major accident.

The engine and gearbox of vehicles in major accidents are generally overhauled, and even the whole power system will be replaced in serious accidents. The damage of the accident car is usually relatively small, generally only the damage of the appearance cover exists, and the vehicle structure will not have much problem.
