The key document is the 机动车登记证书 (Vehicle Registration Certificate), the green booklet proving ownership. Along with it, the seller should provide the 行驶证 (driving license for the vehicle) and their ID. Verification steps: 1. Check that the VIN/chassis number on the certificate matches the car exactly, stamped on the dashboard and door frame 2. The certificate's 所有人 (owner) field must match the seller's company name or the export agent they claim to work with 3. Look at the registration history pages—frequent transfers in a short period can indicate problem cars being flipped 4. Confirm the car is not marked 抵押 (mortgaged/pledged to a bank) Be cautious if the seller only shows photos of these documents and refuses a live video panning across the original booklet with the day's newspaper. Also verify the export company has 二手车出口资质 (used-car export qualification)—a legitimate exporter will share their license number, which you can cross-check on Chinese commerce bureau websites.

Comparing quotes properly means comparing the same thing: 1. Normalize the scope: some quotes include inland transport, export clearance, inspection and ocean freight, others are FOB only. Ask each exporter for a line-item breakdown so you can compare like with like. 2. Check what is excluded: port charges at destination, customs duties, homologation and registration are almost always on you. Get a written list of everything NOT included. 3. Look beyond the number: a quote 10-15% below the market usually means the car has an issue (accident history, rolled-back mileage, pending lien) or the exporter plans to cut corners on inspection and loading. 4. Verify the exporter: business license, export qualification, recent shipment records, and references from buyers in your region. A realistic quote from a verifiable exporter is worth more than a bargain that turns into a dispute. Always pay against milestones with inspection before balance payment.

If there is a minor leak in the lines due to bumps, it is possible that the cooling may not work upon arrival. This is a normal physical loss. The cost of vacuuming, pressure testing, and recharging refrigerant at a local auto repair shop is low and is the buyer's responsibility.
