Unauthorized personnel are prohibited from entering and taking photos inside the roll-on/roll-off ship, but we will provide photos of the vehicles parked in the loading area with the ship in the background. The bill of lading marked "Shipped on board" with the date is the most essential legal proof of loading.

Battery condition is the single most important — and most expensive — variable in a used EV. Ask for a State of Health (SOH) report: in China, dealers and authorized service centers can read it via the manufacturer diagnostic system. It shows remaining capacity as a percentage of the original. Rule of thumb: above 90% is excellent, 85-90% is acceptable for the price, below 80% needs a serious price cut or battery refurbishment. Also get the battery's full charge and discharge history (次数) — a 3-year-old car with 800 fast-charge cycles has lived a harder life than one with 200. Physically, inspect the battery pack enclosure on a lift for dents, corrosion, or coolant leaks. Check that DC fast charging works during a test charge. Finally, verify the battery is not covered by an open recall or replacement program — this is both a risk and sometimes a free upgrade.

An OBD scan is one of the most cost-effective tools in a remote pre-purchase inspection, but you need to know what it can and cannot tell you. What it reveals well: current and stored fault codes across the engine, transmission, ABS, airbag, and body modules. A car with dozens of cleared codes in multiple modules may have electrical problems or a history of tampering. It also shows readiness monitors — if all monitors show 「not ready」 on a car that claims to be freshly serviced, the codes were probably cleared recently to hide something. What it reveals with the right software: live data. You can watch engine idle stability, coolant temperature under load, transmission shift behavior, and battery cell voltages on EVs. Abnormal fuel trims or misfire counters can flag worn injectors or coils before any warning light appears. What it cannot do: prove real mileage (odometers can be corrected digitally), detect physical accident repairs, or judge paint and rust. Practical advice: ask your inspector for a full-system scan report with screenshots, not just a 「no codes」 verbal summary. For Chinese brands, make sure the tool supports their protocols — mainstream scanners cover BYD, Geely, and Chery well, but some small brands need brand-specific software.
