Mainstream Chinese automakers rarely publish official English versions of their underlying circuit diagrams. We can provide some models' original Chinese technical documents (PDF) for B2B clients, which you will need to translate for your local mechanics using translation software.

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.

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).
