Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.

A structured live video inspection can catch most mechanical problems. Ask the seller to do the following in order: Cold start: film the engine bay before starting — check for leaks, cracked hoses, and corrosion. Then start from cold and listen for rattling or knocking during the first minute; abnormal noises on cold start often mean worn internals. Fluids: pull the oil dipstick — milky or foamy oil suggests head gasket issues. Check coolant color and level. Transmission: with the car warmed up, film each gear shift, forward and reverse. Hesitation, harsh jerks, or slipping RPM are red flags. Brakes: test at low speed in a safe area — the pedal should feel firm, not spongy, and the car must not pull to one side. Tires: walk around and film each tire's sidewall and tread. Uneven wear suggests alignment or suspension problems. Combine this with an independent pre-shipment inspection for a professional report — the video call is your first filter, not the final verdict.

The standard set: commercial invoice, packing list, bill of lading, export customs declaration, certificate of origin, and a copy of the vehicle title/registration. How to verify: the bill of lading number should be trackable on the shipping line's website; the certificate of origin is verifiable through CCPIT's online system; and the VIN must match across all documents, the inspection report, and the car itself. Ask for scans of everything before paying the balance, and have a freight forwarder review the set. Mismatched VINs, missing title copies, or vague promises that "documents will follow" are red flags worth pausing the deal over.
