To inspect used cars in detail It is very important to choose to look at the following 4 important points around your car. that you should notice carefully And don't miss it.

Point 1: Nut head

Nut marks must not have tightening marks, removal marks, scratched nut head paint, paint stains, or sliding nut bases.

Point 2: Silicone

The original silicone from the factory will have a clearly convex appearance. The shape is orderly. The silicone body is flexible. When you use your fingernail to poke it, it feels hard. For cars that have been repaired, the silicone lines are not in order. And when you put your fingernail in it, it will feel soft like there are air bubbles inside.

Point 3: background color

Toyota cars and parts are plated to prevent rust using the Electro Deposit Painting process. New cars are plated with a rust-proof gray color, but the parts are black instead. If the car has an accident The replacement part has a black base color.

The way to inspect the parts is by using a flashlight and a mirror to look at the surface paint in the holes. or along the edge of the part

Point 4, weld seam

Welds indicate the replacement of parts that cannot be repaired to their original condition. By cutting and removing to replace new parts by welding.

There are 2 types of welding:

      1. Re-spot welding. If it is a new weld from the Toyota factory, it will have a diameter of 7-8 millimeters, but welds from repairs will have a diameter of 4-5 millimeters.

    2. MIG welding. The Toyota factory does not use MIG welding in production, so it will only occur from the repair process that the weld seam will be convex. Because it is caused by using welding wire to melt multiple layers of steel together.

In addition, there are other noticeable points of welding repairs, including burn marks, rust, and filing marks from welding repairs.
