A professional pre-purchase inspection in China normally covers five parts: exterior and interior condition, a lift inspection of the chassis and frame, engine bay checks, a road test, and OBD diagnostics. Prioritize the chassis rails and A/B/C pillars for cut-and-weld repairs, engine oil leaks and timing noises, transmission shift quality, and OBD fault codes — cleared codes leave telltale history data. For EVs, add battery pack casing, insulation values, and battery state of health (SOH). Insist on original timestamped photos with the VIN visible and a written conclusion such as 'fit for export' or 'major defects found.' A report that only says 'good condition' is not worth paying for.

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).

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.
