There are too many types of vehicle modifications. Those that have been registered do not need to be restored to factory settings, but unregistered parts must be restored. Here is an introduction about modified vehicles: 1. Introduction to modified vehicles: Modifications involve adding, removing, or replacing parts of the original factory model or altering its appearance. Reasonable and scientific modifications can make the vehicle safer to drive and improve its performance. Vehicle modifications are both an expression of personal style and a means to enhance driving performance and safety. 2. Regulations related to modified vehicles: Laws and regulations impose restrictions on vehicle modifications. The vehicle model, engine model, and chassis number cannot be altered, and the vehicle's structural integrity must not be compromised. Changing the vehicle's color, replacing the engine, body, or chassis requires inspection and approval. Replacing the engine, body, or chassis also requires submitting a qualified motor vehicle safety technical inspection certificate. Decals or wraps must not exceed 30% of the vehicle's total surface area; exceeding this limit requires approval from relevant authorities.
