Can a Base Model Car Be Upgraded at a 4S Shop?

After purchasing a vehicle, you can still go to a 4S shop to add optional configurations without any issues. However, modifications involving wiring changes may pose certain safety hazards and risk of malfunctions. Below are some precautions for car modifications: Precaution 1: Installing a larger exhaust reduces exhaust backpressure, which can decrease low-speed torque and may cause the engine exhaust valves to burn out due to excessively high temperatures. Precaution 2: Adding stabilizer bars and tie rods can intensify local vibrations, potentially causing permanent damage to the vehicle body. Precaution 3: Installing thicker ground wires can lead to abnormal high-voltage circuits, shorten spark plug lifespan, sometimes cause computer system confusion, and increase fuel consumption.

It's quite common to buy a base model car and upgrade it at a 4S店. I personally upgraded the audio system and added leather seats to my entry-level sedan, and the whole process went smoothly with their technicians handling it professionally. Some features like navigation or a rearview camera can be added directly, saving a lot compared to buying a higher trim new car. However, be cautious—hardware components like the engine or transmission usually can't be modified due to original design limitations. After the upgrades, the car becomes more comfortable and presentable, enhancing the driving experience. It took about two days, so I recommend scheduling an appointment in advance to discuss the plan. However, major modifications like exterior kits might affect the warranty, requiring a signed agreement. Overall, I think it's worth it, especially for daily commuting needs.

From an economic perspective, upgrading a base model car at a 4S dealership requires careful consideration of costs. For example, when I was on a limited budget, I upgraded fabric seats to leather, spending several thousand yuan, but the interior instantly looked much more premium. Small functional additions like USB charging ports or ambient lighting are relatively cost-effective. Some mechanical components cannot be altered, as modifications would be expensive and reduce resale value. 4S dealerships offer professional services that avoid future issues, making them more reliable than aftermarket modifications. I recommend prioritizing practical upgrades over flashy but impractical ones. While upgrades enhance comfort, in the long run, they may not be as economical as purchasing a higher trim model outright.

Technically, 4S dealerships can perform software and partial hardware upgrades on base-model vehicles. For example, adding cruise control or automatic parking modules, all using genuine factory parts to ensure compatibility. Upgrading electronic systems like installing a larger infotainment screen is also straightforward. However, critical components such as the engine and suspension cannot be modified, as it affects safety and certification. The upgrade process is simple and direct – when I added LED headlights, it only took two hours. Note that unauthorized modifications may cause malfunctions, while 4S upgrades come with warranty coverage.
