Salvage cars refer to vehicles that have suffered damage from non-natural wear and tear accidents, resulting in decreased mechanical performance and economic value. The following scenarios classify a vehicle as a salvage car: 1. Vehicles where the engine compartment or passenger compartment has been damaged due to impact; 2. Vehicles where the rear quarter panel has been damaged by more than one-third due to impact; 3. Vehicles with welded, cut, reshaped, or deformed longitudinal beams; 4. Vehicles with welded, cut, reshaped, or deformed shock absorber mounts; 5. Vehicles with welded, cut, reshaped, or deformed A, B, or C pillars; 6. Vehicles where the airbags have deployed due to impact; 7. Vehicles with severe welding, cutting, reshaping, or deformation in other non-removable parts; 8. Vehicles where the body has been submerged in water exceeding half of its height, or where water has entered the passenger compartment.

An accident car refers to a vehicle that has been involved in a collision or other severe accident, resulting in structural damage. I have personally seen many cases of accident cars where critical structural components like the frame rails and A-pillars are often bent or deformed. This is not something that can be fixed with a simple paint job. Even after repairs, the car may pull to one side or produce strange noises while driving. The most alarming issue is that the airbags might not deploy in the event of another collision. Many people are wary of buying used cars that have been in accidents because their safety is significantly compromised. I recommend checking the vehicle's repair history or consulting someone knowledgeable about cars to inspect it. Accident cars often show signs of re-welding near the VIN, and the glass dates may not match the rest of the vehicle—these are key clues to look for.

A so-called accident vehicle refers to one that has been involved in a major collision, where the frame structure has been directly damaged. Minor scratches and dents don't count. Once when I was helping a relative pick a used car, we came across one that had been hit on the side. The door had been replaced with a new one and looked shiny, but upon peeling back the rubber seal, we found welding marks on the B-pillar. Even after repairs, such damage affects safety, with noticeably unstable handling during high-speed turns. The key issue is that accident-prone cars tend to develop problems after a couple of years—common issues include suspension system noises or door leaks. When buying used, it's best to bring a magnet to check the body. Factory paint will hold the magnet firmly, while areas with filler will have weaker magnetism. These are all practical tips.

An accident-damaged vehicle refers to a car that has suffered significant collision damage, especially to its structural frame. As professionals in auto repair, we know that cars with deformed radiator supports or crumpled longitudinal beams are considered accident vehicles. Although they can still be driven after repairs, metal fatigue occurs much faster than in normal vehicles during high-speed vibrations or when going over large potholes. Some vehicles may have replaced airbags, but if the computer control system doesn't match, the airbags won't deploy during an accident. When inspecting for accident damage, pay special attention to wheelbase measurements and bolt marks - these telltale signs can't be faked.

Simply put, a salvage car is a structurally damaged vehicle that has been involved in a major accident. According to insurance company standards, any car with repair costs exceeding 50% of its value or damage to the A, B, C, or D pillars is considered a severely damaged vehicle. Never touch such cars, as they pose significant risks to the steering system. A colleague of mine bought a refurbished salvage car to save money, and the steering wheel locked up while driving, nearly causing an accident. Although used car platforms are convenient, it's essential to check the insurance claim records and dealership maintenance files. Sometimes, signs of screw removal and reinstallation can reveal hidden issues. Safety is no small matter—it's best to conduct an undercarriage inspection before purchasing.

An accident car, to put it simply, is one that has been involved in a serious collision, resulting in deformation of the chassis frame or the vehicle's structural body. My uncle's car was once rear-ended, and the 4S shop said that if the rear longitudinal beam was deformed, it would be considered an accident car. Later, when he changed cars, he paid special attention to this point, as it concerns the safety of the whole family. The safety performance of accident cars is really not up to par; crash tests show that repaired vehicles can hardly meet the original factory strength standards. Nowadays, many people check the vehicle identification number (VIN) to identify its history before purchasing a used car, then inspect details like whether the front fender screws have been removed or if all the fuses in the fuse box are original. These details can help avoid pitfalls.
