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.

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.

Yes. For bulk purchases, we can organize and package the core historical records (transfer records, maintenance summaries) for each vehicle. If an English version is needed, we can provide a basic machine translation reference, and human translation assistance for key technical terms.
