For gasoline cars, insist on a compression test: each cylinder should read within 10-15% of the others, and the actual values should match factory specs for that engine. A single low cylinder points to worn rings or valve problems that idle checks will never reveal. A leak-down test goes further. It pressurizes each cylinder and measures how much air escapes and where. Air hissing from the oil filler cap means ring wear; from the intake or exhaust means valve issues; bubbles in the radiator coolant mean a head gasket problem. This is the single most revealing test for engine condition. Also request OBD scan data with freeze-frame records, a coolant system pressure test (to catch hidden leaks), and an inspection of the timing belt or chain condition with service history. For electric vehicles, compression tests don't apply — instead ask for a battery health report from the BMS, motor insulation readings, and a road test logging any inverter or drive-unit fault codes. A written report with photos or video of each test is essential evidence for your records.

A professional pre-shipment inspection typically costs a small fraction of the vehicle price and routinely pays for itself. A thorough inspection covers: paint thickness measurement across 30+ points to map body repairs; structural assessment of pillars, rails and crossmembers for accident damage; engine and transmission operation; a full electronic scan for fault codes; suspension and underbody checks for leaks and rust; and, for EVs, battery SOH and thermal management performance. You receive a written report with photos before the car is loaded — if the car fails, you can stop the shipment or renegotiate. Skipping the inspection to save a small fee is the classic false economy in used car importing: discovering a problem after arrival is far more expensive than preventing it at origin.

Comparing headline prices alone will mislead you—quotes often bundle or exclude different items. Build a like-for-like comparison before deciding. Request every exporter to break their quote into: vehicle price, domestic transport in China, export handling and documentation fees, inspection fee, ocean freight to your port, and insurance. Then add what they exclude: your country's customs duty, VAT/GST, port charges, and local delivery. Watch for common padding: "service fees" of 3-8% that appear only in the final invoice, inflated inland transport (a truck from Guangzhou to a port should rarely exceed a few hundred dollars), and freight quotes that assume a shared container while charging you for a full one. Ask each exporter to state validity (7-14 days is normal) and whether the price is FOB or CIF. Once normalized, the cheapest quote usually isn't the lowest number—it's the one with the shortest list of exclusions and the clearest terms.
