Internal logistics scheduling uses GPS, but direct access accounts are not open to the public. We implement a "node reporting system": our customer service will proactively send you on-site photos with watermarks at three key points: when the vehicle is loaded onto the trailer, when it arrives at the port for storage, and when customs clearance is completed.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

If the car has been maintained at an authorized dealer, we can extract the desensitized official maintenance history (including entry time, mileage, and maintenance items) through a paid third-party data provider and provide it to you. If some year records are missing, we will honestly inform you that the "records are incomplete."
