Why we should do the inspection when we buy second-hand car ?

Today's client is a young guy. Just a few years after he started working, he saved some spare money and prepared to buy a second-hand car. Customers were attracted by the unique design of the A5 when they were still in school, so they looked directly at it when buying a car. Then let's take a look at the car selected by the customer.

First of all, we start to inspect the exterior paint and covering parts. The front and rear bumpers are generally made of plastic, which cannot be detected by the coating thickness gauge . At this time, we need our inspectors to use experience to determine whether there are traces of repainted or replacement. There is obvious flying paint on the black plastic parts of the front bumper fog lamp. The cause of this flying paint is mostly that the covering is not properly done when the paint is painted. From this we can see that the front bumper has been painted.

The paint thickness of the left front fender is relatively high, exceeding 1000 microns, but we can see that the fixing screws of the fender have no traces of disassembly. It can be judged that the left front fender has only been repaired by sheet metal and has not been disassembled and 

replaced.

The paint thickness of the left front door is 111μm, which belongs to the normal paint thickness range of A5. When we see the door hinges again, these fixing screws have no traces of removal, so we can judge that the left front door is normal. When inspecting the appearance, remember to not only rely on the coating thickness gauge , but also to make judgments based on your own experience.

The paint surface thickness of the left rear door and left rear fender are 784μm and 597μm, all of which have been repaired by sheet metal.

The paint surface value of the trunk is normal, but there is a large area of scratch damage.

The rear bumper can only be judged by the naked eye, we can observe from the gaps on the edges and the gaps of the rear radar. Sure enough, there were traces of spray paint in the gap of the radar, and the rear bumper was repaired .

The right rear fender has a value of 1449μm and has been repaired by sheet metal.

The paint surface values of the front and rear doors on the right side are 1297μm and 204μm, respectively, with sheet metal and paint, but they have not been disassembled.

The paint surface of the fixing screws of the right front fender was damaged and even rusted. It was obvious that it had been disassembled. The paint surface has a value of 617μm, and has also been repaired by sheet metal.

However, the values at the A-pillar and the threshold are close to 1000. Carefully observe that there are obvious cutting and welding marks on the inside of the A-pillar. It seems that the right A-pillar has received a lot of impact. This is already a serious accident, and it is obvious that you can see Come out, everyone should keep their eyes open when choosing a second-hand car. Don't miss out on such a big accident and the problem is very obvious.
