What are the differences between maintenance at a 4S shop and outside?

[Shelby]

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.
