Many people will hesitate between a new car and a used car when buying a car. The process of buying a new car is more transparent, but there is more room for depreciation in the later period. It is cheap to buy a second-hand car. You can buy a second-hand car with higher configuration at the same price, but it is difficult to guarantee the specific car condition. In particular, some small white novices who have never been exposed to used cars are even more afraid of buying cars that are in poor condition or have accidents.

Today, I will teach you how to identify accident cars better and faster.

In the first step, we need to know what are automobile panels and structural parts, and what are the differences between them.

Automobile structural parts refer to the body frame, which can be understood as the skeleton supporting the body and is the first guarantee of safety.

Automobile skin refers to the skin on the surface of automobile, such as door, fender, hood, front and rear bars, etc., which is similar to human skin.

Structural members include: left A-pillar, left B-pillar, left C-pillar, left D-pillar, right A-pillar, right B-pillar, right D-pillar, left front longitudinal beam, left middle longitudinal beam, left rear longitudinal beam, left front shock absorber seat, right rear shock absorber seat, right rear shock absorber seat and left lower skirt.

As mentioned earlier, the covering parts are like human skin, and the structural parts are equivalent to the skeleton of the human body, which is the focus of carrying the whole vehicle and the first guarantee of safety. Therefore, detecting the integrity of structural components is the main basis for judging major accidents. The damage of structural parts will also affect the safety performance of the vehicle, so it is also based on this to determine whether the used car is an accident car.

If there is an impact in front, the damaged parts of the cover include the front windshield, hood, front bumper and left and right fenders. These parts belong to the cover and can be repaired. If the collision intensity is quite strong, causing injuries to the left front right longitudinal beam, the left front right shock absorber seat, the front panel and the left and right A-pillars, it can be defined as a major accident. Because the structural part is the main part of the car, it has the greatest strength. The materials and processing technology used are also the most complicated, and it is quite difficult to reach the original factory level through post-maintenance, so it can still be judged by careful observation and comparison of every detail.

Look at the side impact.

Covers damaged by side impact include front and rear fenders, front and rear doors and glass. Strong collision will damage structural members, including A-pillar, B-pillar, C-pillar, upper beam and lower beam.

If you want to know whether the cover has been replaced or repaired, just pull open the adhesive tape and observe the replacement or maintenance traces of solder joints. Similarly, if these structural members are repaired, it can be judged that it is a major accident.

Look again and then bump.

The rear bumper, trunk lid and left and right rear fenders were damaged due to rear impact. The collision is stronger, which will hurt the left and right rear side rails and the trunk floor. We should observe whether these structural parts are welded. If it is found that the rear longitudinal beam is repaired, the trunk floor is cut and the rear fender is retreated, it can be judged as a major accident.

Covers that will be injured after the vehicle rolls over and collides include the front and rear windshields and the roof. Having left and right top beams and abc columns will damage structural members. Use the same method to check the damage of the main body, such as metal sheet and cutting marks. It can still be defined as a major accident.

Finally, to sum up, when checking the car, we should learn to infer the state of the structural parts from the damage of the covering parts. If the structural parts are damaged, then the accident point of the car can be clearly determined.

Today, we explained how to judge the accident car from three angles: front, side and back. If you have any better methods or other questions, you can discuss them with us in the comments section.
