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.

Common charges beyond the car price: pre-shipment inspection fee, inland trucking from the car's city to the port, export customs clearance, documentation fee, terminal handling charges (THC), certificate fees, and markups hidden inside the freight quote. How to protect yourself: ask for an itemized quotation with each charge listed separately; compare 2-3 exporters, because a very low car price is often offset by inflated fees; confirm which costs are included up to the port of loading and which you pay at destination; agree in writing on the payment currency and the exchange rate date. Your total budget should be: car price + export fees + freight + insurance + destination port charges + import duties and taxes.

Testing is mandatory. Troubleshooting electrical devices in the car is part of the standard procedure. We will test the window lift motors, mirror folding, air conditioning compressor and fan, electric seat tracks, etc. Any stuttering or failure of electronic components will be recorded.
