Yes, as long as they comply with regulations. More information on legal modifications is as follows: 1. Color change: As China gradually becomes a major automotive country with an increasingly rich car culture, current policies and regulations have been somewhat relaxed. However, seats cannot be altered at will. Although they are rarely checked, changing either the number or functionality of seats (such as installing sport seats) is not allowed. 2. Rims: These can also be modified, but sedans cannot be fitted with sport-style rims that are one inch larger, as such modifications will not pass annual inspections. Brake calipers can be modified, and installing roof racks, entry/exit steps, replacing radiator grilles and bumpers, and changing rims are also legal. However, there are prerequisites for these modifications. Firstly, modifications can be made to the body color, engine, fuel type, and chassis number, among others. Of course, these modifications are not without limits and must adhere to specific regulations.

After buying the car, I still wanted to add some accessories to it, so I installed a GPS navigation system myself. The original car didn't come with this feature, and it's really practical for navigation when going out, saving the hassle of always using a phone holder. I spent over 1000 yuan to buy a high-quality kit from an online store, and then had it installed at a reliable modification shop, which took about four hours to complete. During the installation, be careful with the battery issues; don't mess with the wiring yourself as it could easily cause a fire. I also added a reverse radar, making city parking much more reassuring. But before making modifications, check the warranty terms, as too many changes might affect the original factory warranty. So, I recommend starting with simple additions like seat covers or floor mats—low cost with quick results. Don't forget about laws and regulations; avoid installing exaggerated lights or loud exhaust pipes to prevent fines.

How to View the Left Front Corner Inside the Car?

What to Do When the Tire Won't Come Off During Replacement?

Start by loosening the five bolts on the wheel counterclockwise using a wrench. Once all five bolts are loosened, raise the jack. Remove the bolts from the wheel one by one, and the tire will come off. Next, replace it with the spare tire. For a five-bolt wheel hub, tighten the bolts in a star pattern multiple times. For a four-bolt wheel hub, tighten them in a diagonal sequence multiple times.
