The industry-standard structure protects both sides. Pay 20-30% deposit after signing the contract and verifying the exporter's license—never more. The balance is paid only after your independent inspection report confirms the car matches the contract, ideally against a copy of the bill of lading so the exporter can't ship a different vehicle. For extra protection, tie payments to milestones: deposit on contract, second tranche after inspection passes, final payment when shipping documents are released. Some buyers use escrow services or trade assurance platforms for the first transaction with a new supplier; fees run 1-3% but are worth it for large amounts. Always pay to a corporate bank account matching the exporter's registered name. Keep every agreement in the written contract—verbal promises like 'we'll fix that before shipping' are unenforceable. If an exporter demands 50%+ upfront or full payment before inspection, walk away; that structure leaves you with no leverage.

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.

Air suspension is very delicate. If, after the vehicle has been stationary for about 12 hours, the height on one side of the vehicle drops more than 1.5 cm when measured from the wheel arch to the tire, we will determine that there is a slight air leak in the air spring or distribution valve on that side and warn you of the high subsequent repair costs.
