Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.

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.

We thoroughly rule them out by checking if the cabin wiring harness is melted, if the seat belts have water stains or mold, if there is unusual rust or debris in the seat tracks and cigarette lighter, and by verifying with the insurance company for any "total loss claims." These two types of cars are an absolute sales ban for us.
