As long as it is a regular 4S, every time the vehicle is maintained, computer data will be archived in the store. Even if the vehicle goes to other 4S, as long as it is a subordinate 4S of the same brand, the repair and maintenance records of the vehicle can be found.

This is much more reliable than simply checking the seal on the maintenance manual, because the probability of falsification of the 4S store’s archived records is close to 0.
