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.

It depends on the situation. If the video inspection reveals significant mechanical faults or structural damage not disclosed in the inspection report, the deposit will be refunded 100% unconditionally; however, if the buyer defaults for subjective reasons (such as suddenly not liking the color or financial issues), the deposit will be retained as compensation for taking the vehicle off the market.

For B2B large customer orders, a "sampling + full inspection" dual regulation is adopted. Core parameters (no major accidents, no water damage or fire) are subject to 100% inspection per vehicle; appearance and condition are uniformly graded (e.g., uniformly purchasing Grade A), and panoramic images of all vehicles in the batch along with a core indicators comparison list are provided before shipment.
