A realistic landed cost has five layers: the car price, export-side fees (deregistration, export license, inland trucking to the port), international freight and insurance, destination duties and taxes, and local charges (port handling, inspection, registration). Buyers most often underestimate three items. First, destination duties are calculated on the customs value, which may include freight, so a cheap car can still attract significant tax. Second, port and terminal charges at both ends add up; demurrage fees apply quickly if documents are late. Third, compliance costs such as homologation, emissions testing, or translation of documents can run into hundreds of dollars depending on the country. Ask every exporter for a written, itemized quote to your port, not just an FOB price, and keep a 5% contingency. Quotes that look unusually cheap usually hide costs in the freight or handling lines.

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.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.
