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.

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.

Odors are difficult to convey through images, so our quality inspectors conduct subjective smell assessments and record them. For vehicles with severe smoke or mold odors, if deep ozone sterilization is ineffective, we will downgrade the vehicle and mark the report with a red "Odor Warning" at the top.
