The technician will put the vehicle in neutral on the lift, rotate the wheels, and listen for any abnormal metal gear whine from inside the motor reducer, and check for gear oil leaks at the joints of the reducer housing.

China has centralized vehicle records you can check remotely before paying anything. Ask the exporter for the 17-digit VIN, then request two reports. First, the maintenance history: third-party platforms pull 4S dealership records showing service dates, mileage and repair items. A mileage line that goes down over time is a red flag for odometer tampering. Second, the insurance claim history: it lists accident dates, claim amounts and repaired parts. Heavy claims involving frame rails or airbags should end the deal. Practical tips: run the reports yourself instead of accepting screenshots from the seller, make sure the report date is close to the delivery date, and cross-check with physical wear such as the steering wheel, pedals and seat bolsters, which cannot lie about high mileage. Keep in mind that small private repairs never enter these databases, so combine history checks with a physical inspection before shipping.

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.
