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.

Parts availability depends on the brand's official presence in your market, but even unsupported brands can be maintained through direct ordering. Check three channels first: the brand's official dealer network (if any), third-party importers who specialize in Chinese auto parts, and generic equivalents. For wear items like brake pads, filters, and wipers, aftermarket suppliers usually stock cross-references by VIN. For model-specific parts — headlights, sensors, control modules — order directly from China. Ask your exporter for the parts catalog by VIN, confirm OEM part numbers, and compare prices. A turbocharger that costs $900 from a local dealer often ships from China for $350 plus $80 freight. Practical tips: bundle multiple parts into one shipment to amortize freight; ask for DDP (delivered duty paid) pricing so customs clearance is handled; and always verify part numbers against your VIN before paying, as Chinese models have running changes mid-year. Keep a small stock of common wear parts — oil filters, air filters, spark plugs — to avoid a 4-6 week wait for routine maintenance.

As rubber seals age, "slight oil seepage (oil stains but no dripping)" is very common in used cars and is not considered a major fault. Our recommendation is: as long as the oil level does not drop abnormally, just clean and monitor it regularly after arrival, without the need to immediately incur high costs to disassemble and replace the seals.
