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 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.

A realistic budget has several layers beyond the vehicle price. First, inland logistics in China: moving the car to the export port typically costs $300-$800. Second, export handling: inspection, customs declaration and paperwork usually add $500-$1,000. Third, ocean freight. A 20ft container to most destinations runs $1,200-$3,000 depending on route; RoRo shipping can be cheaper for driveable cars. Add marine insurance, usually 0.3%-0.5% of the car value. Fourth, destination charges: port handling, customs duties, VAT/GST and local registration fees. These vary widely; some countries charge duties of 20%-80% of the vehicle value plus an excise based on engine capacity. Finally, any compliance work: inspection certificates, modifications to meet local standards, or homologation. Ask your exporter for a full CIF quote and have a local customs broker confirm destination taxes before you commit.
