Is it illegal to retrofit an old model with a new front fascia?
2 Answers
Retrofitting an old model with a new front fascia is not illegal, but it must be performed by a qualified professional unit. When submitting the vehicle for re-registration of the driving license at the vehicle management office, proof documents of the modification must be provided; otherwise, it will be considered an illegal modification. Vehicle modification refers to altering the external appearance, interior styling, and mechanical performance of the original prototype vehicle manufactured by the automaker according to the owner's needs. Exterior modifications mainly include stickers, body painting, emblems, front and rear bumpers, body kits, high rear wings, vented engine hoods, window rain guards, HID xenon headlights, headlight decorative panels, front and rear perspective mirrors, lowering the body, etc.
With over a decade of research in automotive regulations, I've found that retrofitting an old model with a new front fascia is only illegal if it violates traffic laws and safety standards. In most countries, including China, vehicle appearance modifications cannot alter key original design elements such as headlight height, bumper shape, or overall silhouette, as this may impact crash safety and regulatory compliance. Minor changes like replacing grilles or trim pieces might be acceptable, but modifying core safety components like headlight positioning or sensor mounts would likely be illegal and require re-inspection approval. From my experience, many owners assume aesthetic modifications are harmless, only to face insurance claim denials due to vehicle inconsistencies or failed annual inspections with fines. Safety comes first—I recommend checking local DMV rules or consulting certified modification shops to assess risks and avoid driving hazards or penalties.
