Advantages and disadvantages of maintenance at a 4S shop and outside: 1. Maintenance at a 4S shop is expensive but guaranteed. There are vehicle inspections for corresponding models, as well as professional technicians and supporting tools and equipment. In terms of spare parts, 4S shops have considerable advantages, with guaranteed reliability and sufficient inventory. Sometimes, replacing certain spare parts or repairs can be done more quickly. 2. Maintenance at external auto repair shops is cheaper but carries higher risks. You have options—you can purchase the engine oil and parts to be used yourself, and you can observe the maintenance process throughout. The disadvantages are also obvious: auto repair shops lack a comprehensive management system and cannot conduct a complete assessment and monitoring of your vehicle. Sometimes, they rely solely on experience to determine which spare parts need to be replaced, and the replaced parts cannot be original factory components.

I used to struggle with this issue too. The biggest advantage of 4S dealership maintenance is professionalism—their technicians are factory-trained and know specific models inside out, even their diagnostic equipment is OEM-matched. Like with my car's unique hybrid system, they can pull up complete service records, use genuine parts for replacements, and trace any issues that arise later. But the costs are really not cheap; even a basic service is about 30% more expensive than independent shops. Independent repair shops are much more flexible—bringing your own oil can save a lot, and familiar owners might even advise which services aren’t urgent. I know a guy, Old Zhang, who’s run an auto repair shop for 15 years; he’s worked on more varied models than 4S technicians. But without access to OEM parts, rare faults still require a trip back to the dealership for computer diagnostics. Now I use a mix: prioritize 4S during the warranty period, then switch to reliable independent shops afterward.

Over the past few years, I've changed three cars and tried different maintenance approaches. The most worry-free aspect of 4S shops is their standardized service – everything from reception to repair progress is transparent, and they even offer free coffee in the waiting area. Once they detected abnormal brake pad wear and replaced the calipers for free. The biggest attraction of independent repair shops is their affordability. Bringing your own full-synthetic oil for minor maintenance can save you 300-400 yuan, and labor costs are much lower too. But finding the right mechanic is crucial. I once went to a newly opened shop to save money, only to have the oil filter not tightened properly, causing leaks and requiring rework. Parts sourcing also requires attention – 4S shops use genuine parts with anti-counterfeit codes, while some so-called 'genuine' parts at independent shops are actually aftermarket, with packaging that looks similar but far inferior wear resistance. My suggestion: choose based on your car's age – new cars are better served at 4S shops to maintain records, while older cars are more cost-effective at reputable independent shops.

As a car owner with ten years of driving experience, I believe the key factors are budget and vehicle type. For high-end cars equipped with complex systems like air suspension, it's best to service them at authorized 4S shops as they have specialized computers for calibration. My neighbor's BMW had suspension height issues after maintenance at a small shop, and the repair costs ended up exceeding the savings. For regular family cars, reputable repair shops are sufficient, but three points require attention: check the maintenance manual for replacement intervals, verify anti-counterfeit codes on parts, and retain service receipts. Time cost should also be considered - 4S shops usually require appointments and waiting, while the repair shop near my home offers immediate service and even provides courtesy cars. Additionally, out-of-network maintenance during warranty period may affect claims - my friend's transmission warranty claim was denied due to using third-party transmission fluid.
