1. Look at the appearance and see if there are any defects.
It is more direct to observe the appearance before buying a car, if the appearance is flawed. If it is an accident car, the kernel may also have problems. Therefore, it is important to observe the appearance. Just like a scar on a person's face, it is too serious to be repaired and maintained with drugs. If you look closely, you can see a little clue. Therefore, if you really encounter an accident car, you must overhaul it. At this time, what you need to pay attention to is whether the gap around the range hood is reasonable and even. The second is whether the line part is more natural. There is also whether the reflected image of the paint surface is uniform. If it is not full-body painting, the image at the joint between the new paint and the original paint will not be so smooth. At the same time, the age of the glass is also an exposed part, so it depends on the factory time. Looking at the appearance with these questions, you can generally see whether the car has been repaired.
2. Open and close the door to see if the operation is smooth.
Try to close the car door, the intention is obvious. Just to see if the car is stable enough when it closes. If the operation is difficult, the door may have been removed. In the meantime, if the door is not closed. It takes a lot of power to shut it down completely, which is also problematic. You can also see that the door frame and the doorpost are parallel, and the place with solder joints should be really round and slightly concave. If the solder joints are rough and uneven, and the paint on both sides of A-pillar, B-pillar and C-pillar has color difference, it is certain that this car should be an accident car.
3. Check the front cabin to see if there are any repair marks at the core.
Before checking the engine, the main consideration is the frontal collision between the two cars, which is the most seriously damaged place. If the situation is serious, the nose wing will be damaged and the basic car will be scrapped. Even if the overhaul cost is high, there will be various problems in the future. Testing this part of the engine is more complicated. There are many places to see, such as the firewall, the inside of the fender and the wheel cover, if there are any signs of repair. Whether the fender screws have been screwed, and whether the putty glue on the wheel cover is applied evenly and neatly can be used as reference materials.
4. Check the trunk to see if there is a hole around the ass.
The purpose of the suitcase and the hood after inspection is the same. From the scene of the accident, frontal collision and rear-end collision are common. If it is really a rear-end car, the trunk is generally worn. At this time, we need to help the trunk floor or the rear tailboard have traces of cutting and welding, or the rear fender liner and the rear shock absorber bracket or seam line. If there is, it can basically be regarded as an accident car.
5. Check the chassis and see what happened to the girder.
Check the chassis mainly considering the bumps of the shaft and other parts. You can find a place to lift the chassis and see if the whole chassis, including the girders, has been renovated or modified. Don't buy it if you have any suggestions, because the broken beam will be renovated later. You can run if you use the car for a long time.
If you have finished the above homework, you still can't concentrate. I suggest you bring a professional mechanic, who will be familiar with it.
