A taillight repaired by rear-end collision is not an accident car. That is, accident vehicles: vehicles whose engine compartment and cockpit have been damaged. The rear fender of the vehicle body hit and damaged more than one third of the vehicles. Vehicles with welded, cut, shaped and deformed longitudinal beams. The shock absorber seat has welded, cut, shaped and deformed vehicles. ABC lists vehicles that are welded, cut, formed and deformed. A vehicle in which the airbag is ejected due to impact. Other non-removable parts are vehicles that have undergone a lot of welding, cutting, shaping and deformation. The car body is soaked in water for more than half of the car body, or the water enters the cockpit. Vehicles whose bodies have been burned by fire for more than 0.5 square meters, and there are still potential safety hazards after repair.
