Start with the owner's manual for your exact model and year—it lists the official service intervals and the required fluid specifications. If the manual is only in Chinese, ask the exporter for the English version, or check the manufacturer's website and owner community forums for your region. After the car arrives, do a baseline service even if the seller says it was just serviced: engine oil and filter, air filter, cabin filter, brake fluid check, coolant, and a 12V battery test. From then on, follow the "severe" or "extreme conditions" schedule rather than the normal one—dusty roads, short trips, and hot or very cold climates all count as severe duty, and intervals are usually shorter. Keep every invoice and record. A documented maintenance history makes warranty claims easier and protects resale value.

Odors are difficult to convey through images, so our quality inspectors conduct subjective smell assessments and record them. For vehicles with severe smoke or mold odors, if deep ozone sterilization is ineffective, we will downgrade the vehicle and mark the report with a red "Odor Warning" at the top.

We cannot open each tire to inspect the inside. However, if a visual inspection reveals severe creases on the tire sidewall, it indicates that the run-flat tire has been driven for a long time at zero pressure, damaging its internal structure. We would recommend replacing it before shipping.
