•Check oil level cold before starting the engine. Any example more than 1,000-1,500 km past its last oil change should be at or near the full mark; if it is not, negotiate hard or walk away

•Verify all NHTSA recalls (accelerator pedal, steering, cooling, inverter IGBT 14V-053, hybrid software 20V-369) are completed via VIN check at nhtsa.gov before handing over any money

•Listen carefully during a brake test for pump cycling noise or grinding from the brake actuator, a €1,200-2,800 repair if failed and out of warranty

•Request a Toyota Techstream hybrid battery health report showing individual cell voltages and state of health

•Run the engine to full operating temperature and check for blue smoke on overrun or when blipping the throttle in neutral, indicating ring or valve stem seal wear

•Inspect the inverter coolant reservoir (separate from the main coolant loop) for correct level and clean color; milky or brown coolant signals inverter cooling problems

•Review service history for oil change intervals; gaps beyond 10,000-12,000 km accelerate ring fouling and oil consumption
