After the accident, many people will face such a choice, plastic surgery or replacement? You will also hear different voices. For the parts limited to plastic surgery and edge changing, insurance companies prefer plastic surgery, because the maintenance cost of plastic surgery will be lower and the claims will be less. For 4S stores, it is more inclined to replace, because the cost of replacing accessories is high and the profit is large. Insurance companies often say that it is not the original car after replacement, and the quality is definitely not as good as the original car. Parts that need to be cut will be said to be very harmful to the car after cutting. 4S shop will say that we are all original parts, and the original parts of the original car are produced by the same manufacturer, and the quality is the same. Replacement is definitely better than plastic surgery.

Here are some metal parts and body parts that can be repaired by plastic surgery, such as front and rear fenders, doors, left and right lower thresholds, hood, roof, front and rear longitudinal beams, etc. For example, headlights and water tanks can't be rebuilt, only new ones can be replaced. From our own point of view, plastic surgery or replacement mainly depends on the degree of deformation of the part. No matter where it hurts, if the deformation is slight, you can do plastic surgery. If the deformation is large, even if it can be repaired, it is best to replace it with a new one. Because of the large deformation, putting it back is equivalent to bending this metal part once, and the strength will be reduced. So how to calculate the slight deformation and how to calculate the serious deformation? There is no specific standard, and the shape of each car is different. You can consult the staff of the 4S shop at that time. Generally, it is considered as slight deformation when the depth is less than 3 cm, and it will be severely deformed even if it exceeds 3 cm. If it is torn or wrinkled, it can't be reshaped.

For replacement, we need to know these things. It is very simple to remove the old parts that are not integrated with the body and install new ones. If it is integrated with the body, it needs to be cut. Cut off the bad part, then cut off the same part on the new part and weld it to the car. It has an impact on the integrity and strength of the car. So in these places, if the deformation is slight, it should not be replaced. If it is serious, it should be replaced because the strength after large area and large deformation is not as good as that after welding. Places like this that need to be cut and replaced are: rear fender, ABC column and lower sill, which are often injured and replaced. If the impact is serious, there are still longitudinal beams that need to be cut and replaced. These places can be defined as accident cars as long as they are rebuilt or replaced. Regardless of the size of the injury, the price of selling used cars will be affected.

Used to replace exterior parts, such as front and rear bumpers, front fenders, machine covers, etc. Although they are original parts, they are all unpainted. After the accessories come, they need to be painted by the 4S shop. Therefore, it is necessary to check the paint surface and assembly process when picking up the car. See whether the paint surface is smooth, whether there is color difference, whether the assembly is fit, and the gap is small while the gap is large.

If you repair your car by insurance, you'd better go to a 4S shop with a resident adjuster and an insurance company, so basically everything can be done as long as you communicate with the 4S shop, and the shop will communicate with the insurance company. There will be no situation where the insurance company's fixed loss amount is small and the 4S shop's asking price is high. If it is not insurance, then the severely deformed part should also be replaced, especially the body part. After repair, the strength is not enough. Another impact will cause serious deformation and will not protect us.
