What to Check on a Used Car Test Drive

A proper test drive is more than a spin around the block. Give yourself 20+ minutes on varied roads, keep the radio off so you can listen, and run through this list.

Startup

• Start the car cold if possible — hard starting is easier to catch when the engine hasn't been warmed up.
• Watch the exhaust on startup: blue smoke suggests burning oil, white smoke can mean a coolant problem.
• Confirm the warning lights cycle on, then the check-engine light goes out.

Engine and acceleration

• Accelerate firmly on a safe stretch — listen for knocking or pinging, and feel for hesitation.
• The engine should pull smoothly without losing power or surging.

Transmission

• Automatic: shifts should be smooth and timely, with no slipping, jerking, or delay when it changes gears.
• Manual: the clutch should engage smoothly (not too high), with no slipping or grinding between gears.

Brakes

• Brake firmly on an empty road — the car should stop straight with no pulling to one side.
• No grinding, squealing, or pulsing through the pedal.

Steering and suspension

• On a straight, level road, ease your grip — the car should track straight, not drift.
• No vibration in the wheel at speed (a sign of alignment or tire issues).
• Go over a bump: listen for clunks or rattles that point to worn suspension.

At various speeds

• Drive both city streets and a highway stretch — some problems only show up at speed.
• Try a tight turn both directions and listen for clicking (a worn CV joint).

If it drives clean and passed your walk-around, it's a strong candidate for a pre-purchase inspection. Browse local listings to line up your test drives.
