It's said that the staff who make Lexus can touch the subtle differences on the body with their hands. It's very difficult for us to reach similar level without professional training, but you don't need to worry too much. After all, as long as a car reaches the factory standard, it's not easy to have defects visible to consumers.

Secondly, we need to observe the gap and flatness between the various covers.

As for the gap, the standards of every main engine factory are not the same, which is related to the brand positioning. After all, it is not realistic for you to achieve the same level of Feidu as level e. the cost is in front of you, and the gap needs to be faced up to. The gap will be more even for the car models with good matching of covering parts, that is to say, there is no smaller or larger situation. If you have a pair of feeler gauges on hand, it's a professional approach. However, it's simpler and more commonly used to take a little thumb and touch along the gap to feel if it's even.

It's also important to say that some gaps in the car body will be designed to be larger due to safety factors. At this time, you don't need to worry about whether the sheet metal quality is unqualified. Some positions, such as the engine compartment cover and the fender, if the thumb can be plugged in, it will definitely indicate that there is a problem with the assembly level.

As for the flatness, a simple judgment method is to touch the overlap of the front cover and the fender by hand. The left and right sides should be the same without any asymmetry. In addition to the large positions of the front cover and fender just mentioned, you should also pay attention to the small details of the fuel tank cover, which often exposes the carelessness of the manufacturer. First of all, touch the surface of auto parts to see if there is any pit, which is easy to be ignored, but also very important. After leaving the factory, BIW comes to the painting workshop through electrophoresis and other processes. At this time, the surface may have small irregular bulges. In order not to let it affect the spraying effect, the staff will make a careful inspection and handle the defects with special tools. Of course, some defects of the reviewer can't be found in time, so you need to touch them by yourself.
