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.

Unauthorized personnel are prohibited from entering and taking photos inside the roll-on/roll-off ship, but we will provide photos of the vehicles parked in the loading area with the ship in the background. The bill of lading marked "Shipped on board" with the date is the most essential legal proof of loading.

Based on practical risk assessment, we strongly recommend setting aside 3% to 5% of the car price as a buffer fund for even the highest-rated used cars, to cover oil changes, new tires, minor shipping scratches, and local inspection labor costs.
