Request a live video call during the test drive rather than a pre-recorded one. Cold start first: listen for rattling or metal scraping in the first seconds — possible timing chain or hydraulic lifter issues. During acceleration, a whining from the gearbox area can mean bearing wear; hesitation or jerking in an automatic suggests transmission problems. Braking: the pedal should feel firm, not spongy, and the car must not pull to one side. Turn the wheel fully in both directions and listen for clicking — a classic CV joint fault. Insist on a highway segment too: vibrations above 100 km/h often point to unbalanced wheels or bent rims. Ask the driver to film the dashboard throughout — warning lights that flicker on briefly are still faults that OBD will record.

From a technical perspective, China's "National VI B (China VI-b)" is one of the strictest emission standards globally, with limits on carbon monoxide, nitrogen oxides, and particulate matter that are even stricter than some of Europe's Euro VI standards. However, the two are not legally recognized by each other, depending on your country's import regulations.

A clean title check has three layers. First, run the VIN through maintenance records: dealers in China log service visits with mileage, and gaps or mileage rollbacks are red flags. Second, pull insurance claim history — major accidents, fire and flood damage usually leave claim records even if the car was repaired well. Third, verify registration status: confirm the car is not under finance, court seizure, or theft report. From overseas, you can engage a local inspection agency or law firm to retrieve these records and issue a written report. Cross-check the VIN and engine number on the report against the registration certificate; any mismatch means walk away.
