How to inspect a used car before buying
To inspect a used car before buying, see it in daylight with a cold engine, walk around it for rust, uneven gaps and mismatched paint, check the tires, fluids and every light, and drive it on both slow streets and a highway. Then pay an independent mechanic for a pre-purchase inspection. Walk away from any seller who will not allow one.

How to do it
- Run the vehicle identification number through a vehicle history report before you travel to see the car.
- Arrange to see it in daylight, and ask the seller not to start it before you arrive so you hear a cold start.
- Walk around it: look for rust, uneven panel gaps, paint that does not match and fresh undercoating hiding rust.
- Check the tires for even wear, the oil and coolant for color and level, and the ground under the car for drips.
- Test every light, the air conditioning, the heat, the windows, the locks and the seat belts.
- Start it yourself and listen for knocks, squeals or smoke from the exhaust.
- Drive it for at least 20 minutes on slow streets and a highway, and test the brakes firmly in a safe spot.
- Check that the title name matches the seller's ID and that the title is not marked salvage or rebuilt unless you knew that.
- Book an independent pre-purchase inspection, then use anything it finds to negotiate or walk away.
Stop and call a professional if
- Always: have an independent mechanic you choose inspect the car before you pay.
- The history report shows flood, salvage or odometer problems.
- The seller cannot produce a title in their own name.
Common mistakes
- Falling for the car on the first look and skipping the inspection.
- Viewing at night or in the rain, which hides dents and paint problems.
- Letting the seller warm the engine up first, which can hide starting problems.
- Trusting the seller's mechanic instead of choosing your own.
- Handing over cash before the title is signed and in your hands.
