Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

Fake or recycled inspection reports are a real risk. Verify authenticity before wiring the balance payment. First, match the VIN: the report must show the full VIN, and the photos must include close-ups of the VIN plate on the chassis and the windshield tag. Ask for a live video call where the inspector walks to the car, shows the VIN tag, and then pans across the dashboard, odometer, and any defects noted in the report—on the same call. Check metadata: ask for original photos rather than screenshots. Files sent via WeChat often strip EXIF, so request the inspector to email originals or use a cloud link where timestamps and GPS data are visible. Cross-verify details: the odometer reading in the video should match the report exactly, and paint-thickness readings should be reproducible—ask the inspector to re-measure 2-3 spots live. Use a known inspection company rather than one recommended solely by the seller, and pay the inspector directly. An independent inspector has no incentive to hide defects.

Ask for a specific set of photos and video taken with the car on a lift — generic walk-around videos will not show what matters. Request close-ups of: the sills (rocker panels) on both sides, front and rear subframes, suspension mounting points, brake lines, and the floor pan under the carpets. Surface rust on bolts is normal; bubbling paint, flaking metal or fresh undercoat sprayed over corrosion are warning signs. Also check for flood damage, a common hidden problem: look at the spare wheel well for water marks or mud, pull up the trunk carpet, and check the seat rails and seat belt buckles for rust or silt. A musty smell reported by the inspector is a red flag. A trustworthy exporter will provide a lift inspection report listing measured paint thickness on structural areas. If they refuse to put the car on a lift, treat that as an answer in itself.
