Ask the exporter for a copy of the vehicle registration certificate (机动车登记证书). It lists every owner change and any mortgage registration. If the car was financed, there will be a lien entry; make sure a release entry follows it. You can also verify the VIN against public records through the traffic management platform (12123) — a legitimate exporter can generate a status report on the spot. Check that the seller's company name on the invoice matches the registered owner. For extra safety, require a written statement that the vehicle is free of liens, loans, court seizures, and lease agreements, and wire payment only to the company's corporate account after ownership is transferred to the export entity. That sequence — transfer first, payment second — is your strongest protection.

Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.

Battery condition is the single biggest value factor in a used EV, and it can be measured — do not accept a verbal "battery is fine" without data. First, ask for a battery health certificate: brands like BYD, NIO, XPeng and Li Auto can generate an official state-of-health report from the VIN, usually within minutes at a dealer or via the brand's app. Look for SOH above 85% for a car under five years old. Second, request a charge-and-discharge test during inspection: the displayed range at 100% charge compared with the original rated range gives a practical health estimate. Third, check battery warranty status. Most Chinese brands offer 8 years or 150,000–200,000 km on the battery pack, and the remaining warranty usually transfers with the car — get this in writing. Fourth, for cars heading to hot climates, confirm the battery cooling system works; overheating is a common killer of battery life. Add a minimum SOH guarantee to your purchase contract so you have recourse if the battery underperforms.
