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.

We will remove the chassis guard to physically inspect the battery pack's lower shell for serious dents or scratches, and check for signs of mud or sand intrusion in the waterproof vent at the edge of the battery pack.

The industry-standard structure protects both sides. Pay 20-30% deposit after signing the contract and verifying the exporter's license—never more. The balance is paid only after your independent inspection report confirms the car matches the contract, ideally against a copy of the bill of lading so the exporter can't ship a different vehicle. For extra protection, tie payments to milestones: deposit on contract, second tranche after inspection passes, final payment when shipping documents are released. Some buyers use escrow services or trade assurance platforms for the first transaction with a new supplier; fees run 1-3% but are worth it for large amounts. Always pay to a corporate bank account matching the exporter's registered name. Keep every agreement in the written contract—verbal promises like 'we'll fix that before shipping' are unenforceable. If an exporter demands 50%+ upfront or full payment before inspection, walk away; that structure leaves you with no leverage.
