It is illegal to change the logo of a car, but you will be punished if you are caught.

According to the "Motor Vehicle Management Measures", the logo must be consistent with the vehicle model and must not be misappropriated. Once found, it will be handled in accordance with the provisions of the national "Technical Conditions for Motor Vehicle Operation Safety". If you are investigated by the traffic police, you will face a fine ranging from 20 yuan to 200 yuan. It is not illegal to change color only on the logo, and the color change of the logo does not need to be filed, because the color change area of the logo does not exceed 30% of the body area.
