Strict definition: All metal body parts (doors, hood, fenders) and the frame must retain the original factory paint, with uniform paint thickness readings. Minor touch-ups or replacements of plastic bumpers, as they do not affect metal corrosion protection and vehicle structure, can still be classified as "original paint" in a broad sense, but we will separately note the condition of the bumper.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

A proper inspection covers roughly 200 checkpoints in four areas: 1. Body and paint: panel gaps, paint thickness readings, signs of accident repair. 2. Mechanical: engine health report, transmission behavior, suspension, underbody on a lift, fluid condition. 3. Electronics: full OBD diagnostic scan, airbag history, all lights and comfort features. 4. Documentation: VIN matches everywhere, no lien or seizure record. You can book directly with inspection companies in Guangzhou, Shanghai, or Tianjin (typically USD 100–250) without going through the seller—give them the yard address and car details, and they send a report with photos and video within 1–2 days. Pay the inspection fee yourself so the inspector answers to you, not the exporter.
