Should Car Modifications Be Done Before or After License Plate Registration?

[Nina]

First register the license plate, then proceed with modifications. Detailed Explanation: Currently, China's policies on car modifications are relatively restrictive. For example, the government allows modifications such as "gasoline to natural gas conversion" and "interior replacements," but major modifications in other areas are not permitted. This leads to issues with license plate registration for modifications in non-approved areas. If unapproved modifications are performed, the vehicle will not be eligible for license plate registration or annual inspections. Additional Information: Regarding annual inspections for modified vehicles after registration, when the periodic inspection comes up, the car can be handed over to a "vehicle inspection agent." If the owner insists on handling the inspection personally, the vehicle must be restored to its original condition before passing. Additionally, cars require regular annual inspections.
