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.

Ask the exporter for a paint thickness gauge report, or request a live video where they measure the car in front of you. What to look for: · Factory paint on most Chinese cars measures 80–120 microns. Readings above 150–200 microns on a panel usually mean repainting; above 300 microns often means body filler (putty) underneath. · Inconsistent readings between panels (e.g., left door 95µm, right door 180µm) suggest the right side was repaired. · Check gaps between panels (doors, hood, trunk). Uneven gaps or misaligned headlights/bumper clips point to past collision repairs. · Look for overspray on rubber seals, plastic trim, or inside door jambs — a clear sign of repainting. · Check bolt heads on fenders, doors, and hood. Wrench marks or fresh paint over bolts mean the panel was removed. Combine these checks with an OBD scan for airbag or crash-related fault codes. Any repainting should be declared by the seller; if discovered undeclared, you have grounds to renegotiate or reject the car.

It's not mandatory. Four-wheel alignment and dynamic balance are part of routine maintenance. During long-distance towing and sea transport, the suspension may experience slight changes in stress. We recommend that buyers perform a four-wheel alignment locally after picking up the vehicle at the destination port and replacing tires suitable for local road conditions.
