Test Driving a Used Car: 10 Things to Look and Listen For

Test driving a used car is one of the most important steps in the car-buying process. Whether you're buying from a dealership or a private seller, the test drive gives you the chance to evaluate how the vehicle performs in real-world conditions. Unlike a new car, a used vehicle comes with its own history-and potentially, hidden issues. That's why a careful, attentive test drive is essential.


Use this checklist to evaluate how a used vehicle performs before buying.

When you shop at a trusted used car dealership like AutoNation USA, you'll often find that vehicles have already gone through a rigorous inspection process-but it's still critical to do your own evaluation behind the wheel.

1. Start-Up Behavior

When you first turn the key or press the start button, pay attention to how the engine turns over. A used car should start smoothly without excessive cranking or strange noises like knocking, clicking, or grinding. Also, check the dashboard for warning lights that stay on after ignition-these can indicate electrical or engine issues.

2. Engine Noise and Vibration

Listen closely to the engine both at idle and under acceleration. It should run relatively quietly and smoothly. Loud ticking, knocking, or sputtering sounds could indicate mechanical problems. A smooth engine is a good indicator that the car has been properly maintained.

3. Transmission Response

If you're test driving a used car with an automatic transmission, gear changes should be nearly unnoticeable. Any jerking, delayed shifting, or slipping between gears may signal a transmission issue. In a manual vehicle, the clutch should engage cleanly and the gearshift should feel firm and precise.

4. Brake Function

Test the brakes under both gentle and firm pressure. The car should stop in a straight line without pulling to one side or making grinding or squealing noises. Pulsations or softness in the brake pedal could mean worn pads or rotors-both costly to fix.

5. Steering and Handling

Take the car through a variety of driving conditions-turns, hills, and highways. The steering should feel responsive and accurate without excessive play. Listen for clunks or knocks over bumps, which might indicate worn suspension components.

6. Acceleration and Power

The car should accelerate smoothly and consistently. If it feels sluggish, hesitates, or struggles when merging or climbing hills, there could be underlying engine or fuel system issues. A properly functioning used car should feel capable and confident.

7. Air Conditioning and Heat

Turn on the air conditioning and heat to check their performance. You should feel cold air quickly from the A/C and warm air from the heater. Unusual odors or poor airflow could signal problems with the HVAC system or cabin air filter.

8. Interior Comfort and Electronics

Inspect everything inside the cabin. Do all windows, locks, mirrors, seats, lights, infotainment systems, and buttons function correctly? A test drive of a used car should include testing these electronics, as repairs can be both annoying and expensive.

9. Suspension and Ride Quality

As you drive over bumps, potholes, or rough roads, note how the suspension absorbs impact. The ride should be firm but not harsh. Excessive bouncing, rattling, or a "loose" feeling can be red flags for shocks, struts, or suspension bushings.

10. Unusual Smells

Pay attention to any strange smells coming from the engine, vents, or under the car after driving. Burning oil, coolant, or rubber smells can be early warnings of leaks or worn parts. A clean, neutral-smelling cabin is ideal.

Make the Most of the Test Drive

When it comes to test driving a used car, trust your senses and instincts. Look, listen, feel-and don't be afraid to take notes. If something seems off, ask questions or request a pre-purchase inspection from a trusted mechanic.

Use this checklist to evaluate how a used vehicle performs before buying. It could save you from unexpected repair costs or buyer's remorse down the line.
