•Connect a hybrid-capable OBD-II scanner and check each hybrid battery module's state of health and voltage balance

•Check oil level on the dipstick and inspect for milky or sludgy oil indicating neglected maintenance or head gasket issues

•Start the engine cold and listen carefully for VVT-i timing rattle in the first 10-30 seconds

•Request full service history and confirm oil changes were performed at or below 8,000 km intervals

•Test drive at varying speeds to confirm the hybrid system transitions smoothly between EV and engine modes

•Check exhaust for blue or grey smoke under light acceleration and on overrun, indicating piston ring wear

•Ask how the car was charged and driven day to day; cars habitually driven on near-empty battery or in extreme heat show faster battery degradation
