Is it better to maintain a new car at a 4S shop or outside?

[VonCorey]

Maintenance and repairs should preferably be done at a 4S shop to ensure after-sales service. For vehicles out of warranty, maintenance can be done outside for lower costs, but it is recommended to replace transmission fluid, differential oil, and fuel filters at a 4S shop for better assurance. Pros and cons of 4S shops and repair shops: 1. 4S shops: They are more professional, capable of comprehensive problem assessment, but may suggest replacing entire parts for minor issues. 2. Repair shops: They are cheaper and more experienced with minor problems, specializing in certain models, ensuring a certain level of professionalism and offering relatively official solutions. However, their skill levels vary, lacking specialization for certain vehicles and professional equipment, and after-sales service may not be well guaranteed.
