What is the difference between 4S shop maintenance and external maintenance?

[MariaRose]

The differences between 4S shop car repair and external car repair are as follows: 1. Different materials used: 4S shops use original factory materials and original factory parts; external repair shops use brand parts, which are aftermarket parts. 2. Different repair quality: 4S shops are more proficient in repairing cars of their own brand, and their after-sales service is limited to a few models of the same brand, with high proficiency; external auto repair shops have less experience, and the repair quality varies. 3. Different warranty: Consumers at 4S shops can receive all value-added services related to car information, market trends, after-sales service, maintenance instructions, parts supply, etc. Whether it's the whole car or parts, they can guarantee original factory products, relieving consumers from worries about after-sales service, repair, and maintenance; external repair shops generally do not provide warranty.
