Brake Fluid:

DOT 3 or DOT 4 (confirm with manual).

Power Steering Fluid:

Dexron III or equivalent ATF (confirm with manual).

Engine Performance:

Occasional rough idle, misfires due to worn ignition components (spark plugs, coils/wires) or fuel injector issues. Timing belt inspection/replacement is critical (non-interference engine, but damage can still occur).

Transmission Durability:

Manual transmissions generally robust; automatic transmissions can experience wear in valve bodies or torque converters with high mileage. Clutch wear is normal for manual transmission.

Suspension And Steering:

Worn bushings, ball joints, and tie rod ends are common with age and mileage, leading to knocking sounds or imprecise steering.

Electrical Faults:

Corroded grounds, failing alternator, or intermittent issues with window regulators and door locks can occur.
