Key documents to request and verify: 1. Export declaration (报关单): proves the car legally left China. Check the VIN, model and exporter name match the car. 2. Commercial invoice: must match your payment amount; customs uses it to assess duties. 3. Bill of lading: confirm the consignee is you or your agent, and the VIN/container number is correct. 4. Certificate of origin: needed for tariff preferences in some markets. 5. Condition/inspection report: ideally from an independent third party, with photos and dates. Verification tips: cross-check the VIN on every document — any mismatch causes customs holds. Ask your destination customs broker to review scanned copies before the car ships, and release the final payment only after documents pass that review. A legitimate exporter will provide all of these without hesitation.

Currently, in most developing countries, there is a severe lack of deep repair capabilities for the three electric systems. We recommend that B2B car dealers must have basic electrical insulation testing capabilities.

Interior wear is harder to fake than an odometer and often reveals true usage better than any document. Focus on high-contact points the seller rarely restores. The driver's seat bolster shows creasing and cracking by 80,000-100,000 km even with covers. Steering wheel leather polishes smooth and darkens with hand oils; a shiny wheel with low claimed mileage is a red flag. Pedal rubbers wear through at similar rates — check accelerator, brake, and clutch depth. Second-row wear patterns tell you how the car was used: heavy child-seat indentations suggest family use (usually gentler), while uniform rear wear with clean front suggests commercial or ride-hailing duty. Check seat rails for rust (indicates water ingress) and look under floor mats for moisture staining or musty smell — flood cars often hide it there. Also examine the infotainment and instrument cluster: Chinese EVs log usage data internally, and a dealer diagnostic readout can cross-check driving hours against mileage. Request close-up, well-lit photos of these specific points during your live video inspection rather than relying on the seller's gallery.
