Check the engine, turbocharger, automatic transmission, 4WD system, differential, transfer case, suspension, steering, brakes and cooling system.
For diesel models, inspect injector condition, turbo performance, DPF system where fitted and service history. Check the chassis carefully for accident repairs or off-road damage.
Also inspect the air suspension on TZ-G-type configurations, electronic equipment, cameras, sensors, sunroof and Toyota Safety Sense functions.
Finally, verify auction records, registration documents, chassis number and mileage. A professional pre-purchase inspection is strongly recommended.
