1. Is the paint painted or sheet metal?

2. Have the fixing screws been removed?

3. Whether the original solder joint exists.

To identify a used car, it is best to look around the car first, and look at the lines and seam width of the car.

Second-hand car identification is actually a reasoning process.

Checking whether the paint surface is painted or sheet metal can infer whether there is an accident at the inspection site or just rubbing the paint.

Removing the fixing screw can indicate whether the component has had an accident.

If the above two points exist, it is necessary to further infer the size and intensity of the accident from the outside to the inside of the car.

The original solder joint is an important basis for judging side accidents and cutting.

Let's take a car as an example to interpret it in detail:

Starting from the front of the car, check the engine compartment first. The engine compartment should check the following aspects:

1. Did the engine compartment cover be removed by painting the original car?

This hood has been removed, and whether it is to be painted, sheeted or replaced needs further identification. 2. Whether the hanging tower top screws are removed and whether the original solder joints exist.

The red circle is the top of the front suspension. Whether the screw is tightened or not and whether the original solder joint exists are the key points of inspection. 3. Whether the fender screws are removed and whether the fender is cut.

There are traces of knocking on the fender bracket of this car, and the screws are also removed. The car had an accident. 4. Have the engine foot screws been removed? Have the screws on the engine been moved?

The engine must be fixed to the frame with these anchor screws. If you want to repair the engine, you must take it apart. These screws are the key.

Look at all the other screws on the engine. If there is disassembly, the problem of this car is not small. Don't touch the engine, gearbox and chassis. It's better not to touch this car.

5. Whether the water tank frame screw has been moved. Whether the radiator of water tank is replaced.

The screw is obviously screwed, so it is urgent to check whether the water tank and radiator are replaced and whether the bumper is damaged. 6. Whether the front bumper is replaced and whether the fixing screws are moved.

There is a screw in the box to connect the front bumper with the front longitudinal beam. When this screw moves, it means that the front bumper has been removed, and it also means that there is something wrong with the front of the car. The following is the profile.

7. Whether the door is removed and whether the original solder joint of the door frame is normal.

This door is obviously disassembled, and there are traces of knocking, indicating that the accident is not light. This is the solder joint of the car door frame, which is round and smooth. If the solder joint is gone or cut, the car can't be taken down. 8. Whether the whole car glass and its headlights are replaced.

Rear of vehicle:

9. Whether the trunk is removed and whether the rear bumper is replaced.

The trunk lid of this car has not been opened. 10. Does the original solder joint of the rear panel exist and the spare tire groove is complete?

That's what happened to the rear fender accident. There should have been an accident at the rear of the car. If all the above parts are checked and all are normal, then this car at least shows that there has been no serious accident.

If you master the ten steps of second-hand car identification, you can also avoid 70-80% accident cars.
