Maintain objective expectations. Vehicles over 5 years old inevitably show signs of decreased paint gloss, slight aging of rubber seals, irreversible patina on interiors, and surface rust on chassis components. As long as core structure and mechanical failures are not involved, these are normal depreciation characteristics over time.

A Certificate of Origin (CO) is an official document stating where the vehicle was manufactured. For imports from China, it matters more than many buyers expect. First, customs value: many countries apply duty rates based on the country of manufacture, not where you bought the car. A CO proves the vehicle is Chinese-built, which determines the correct tariff line—skipping it can mean reassessment, fines, or seizure at destination. Second, trade agreements: some countries have preferential tariffs for Chinese goods that only apply with a valid CO. Request a CO issued by the China Council for the Promotion of International Trade (CCPIT) or China Customs, not a self-printed form. Check that the VIN, engine number, and buyer details match your purchase documents exactly. Make receiving the CO a condition before your final payment, and keep the original—customs at destination will ask for it.

Strict definition: All metal body parts (doors, hood, fenders) and the frame must retain the original factory paint, with uniform paint thickness readings. Minor touch-ups or replacements of plastic bumpers, as they do not affect metal corrosion protection and vehicle structure, can still be classified as "original paint" in a broad sense, but we will separately note the condition of the bumper.
