The customs of the destination country has the right to disregard the commercial invoice and reassess the value based on its internal database (such as the customs valuation red book). Any additional duties incurred are a result of the importing country's policy and are fully borne by the buyer (importer).

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.

We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.
