How to test drive a used car: what to listen for, feel for and try

Plan the drive

• Ask for at least twenty minutes, and a route with city streets, a highway and a hill if possible.
• Bring your insurance information and your driver's license. The seller will want to see them.
• Start with the car cold, so you can hear how it starts.

Before you drive off

• Adjust the seat and mirrors, and check you can see well in every direction.
• Turn the key and watch the dashboard: warning lights should come on and then go out.
• Check for smoke from the exhaust, and listen to the engine at idle. It should be smooth.

What to feel for while driving

• Steering. The car should go straight when you let go lightly of the wheel, without pulling to one side. There should be no shaking or slop.
• Brakes. In a safe place, brake firmly. The car should stop straight, without pulsing, squealing or a spongy pedal.
• Acceleration and shifting. Shifts should be smooth, with no slipping, harsh jerks or long delays. The engine should pull steadily.
• Suspension. Drive over bumps and listen for clunks or rattles. The car should settle quickly, not bounce.
• Highway speed. Check for vibrations in the wheel or seat, wind noise and stability.

What to listen for

Turn the radio off. Listen for knocking or ticking from the engine, squealing from belts or brakes, grinding when you brake or turn, humming that rises with speed (a sign of wheel bearings) and clunks from the suspension. Note when each noise happens and ask about it.

Try every feature

Test the air conditioning and heat at every setting, the windows, the locks, the lights, the wipers, the cruise control and the infotainment system, and park the car and check that the parking sensors and camera, if it has them, work.

Check it again afterward

When you get back, park, leave the engine running and look under the car for new drips. Look at the temperature gauge and listen for anything that changed after the engine warmed up.

Take notes and take your time

Write down what you noticed. Then do not decide on the spot. A good car will still be there after you have slept on it and had a mechanic look. See how to inspect a used car.
