Old car models can be modified to new models and registered. The following are the precautions for vehicle modification: Prohibited modifications: Car power, lighting, operation, exhaust emissions, cooling, braking, muffler, suspension, steering system, exterior structure, tires, rims, etc. When modifying a car, it is essential to pay attention to certain key parts. During car modification, it is important to avoid installing oversized rear wings, enlarging car rims, or ignoring safety devices such as car bumpers. Allowed modifications: Changing the body color, replacing the engine (limited to the same model and type, only original factory), replacing the body or frame, and replacing the entire vehicle due to quality issues. Registration change time: Within 10 days after body modification, you must apply for a registration change at the vehicle management office.

I learned from a friend that whether a car can be registered after modifying an old model into a new one mainly depends on the extent of the modifications and local regulations. If it's just surface changes like replacing the front grille and headlights, adding a spoiler, or modifying the body kit, most don't require registration. However, altering the chassis structure or key components, such as installing a different model of engine or chassis, may trigger legal issues. In China, the "Road Traffic Safety Law" stipulates that vehicles cannot alter their factory-registered identification features, including the chassis number and overall model type. Therefore, major modifications are generally illegal and can easily lead to penalties like fines and demerit points if caught by traffic police. In car enthusiast circles, I've seen many people modify their cars for novelty, only to fail the annual inspection and have to revert the changes, wasting money and causing hassle. For safety, it's best to consult traffic authorities or professional modification shops beforehand to confirm the list of allowed changes and avoid penalties or accidents on the road.

Last year, I wanted to upgrade my old car to look like the new model, so I changed the grille and interior, thinking it was no big deal. But when I went to the vehicle management office, they said it constituted altering the vehicle's characteristics and had no record of such modifications, so they outright rejected it. After a lot of hassle, I finally learned that minor parts like rims or light covers could be adjusted, but imitating the entire new design might be illegal. Now, I drive more carefully, as illegal modifications carry significant risks: not only would insurance not cover any accidents, but safety defects could also cause problems. I advise everyone to check the regulations before making changes—don’t end up like me, wasting time and effort while putting yourself in danger.

I usually do some car modification work, and clients often ask if old cars can be registered after being modified to look like new models. It depends: modifications like repainting or changing bumpers are generally fine; but replacing the engine with one from a different year or making major body alterations might be rejected, as regulations prohibit altering core components. For registration, you need to provide the original car documents and a modification report, and it's best to have a professional testing agency check for safety. Illegal modifications won't be allowed on the road.

This is quite risky: After illegally modifying the new style, all accident liabilities fall on you, insurance may become invalid, and the annual inspection will definitely fail. A buddy of mine tried modifying the front of his car, ended up being stopped by traffic police, fined, and had to restore it to its original state, costing double the money. It's advisable to first assess the scope of modifications, consult the local vehicle management office, and ensure compliance.
