  • If the seller refuses to allow you to thoroughly examine the car or take it to a mechanic, walk away.
  • Examine the engine, brakes, transmission, suspension, tires, and interior.

After Completing a Check

After completing a thorough check of the vehicle you're interested in, go ahead and do the following:

  • Talk to the seller about any issues you noticed. If you're still interested in the car, see if they're willing to bring down the price.
  • Talk to your mechanic about how expensive fixing any issues would be.
  • Walk away from any car that has excessive damage or that doesn't feel safe to drive.
  • Take a couple of days to think over your decision. Don't impulse buy.
  • Consider asking the seller to take the car down to a mechanic to have them examine it. If they refuse, it likely means they have something to hide. Walk away.
  • Research what price cars of that make, year, and model sell for. Consider how any existing damage or issues impact the price.
  • Negotiate with the seller as needed.
  • Once you have the money ready, let them know you're interested in making an offer.
  • If the seller accepts your offer, congrats! This car is now yours.
  • Once the car is in your ownership, fix any outstanding issues as soon as possible. Get it cleaned up, both inside and out.
  • If you had to take out a loan for this car, make sure you keep on top of payments.
