What do I need to sell my car to CarMax?
Requirements can vary from state to state, but there are a few items you'll need no matter where you are:
Your car's title or payoff information. All titleholders should be present.
Valid and current registrations
Valid state-issued photo ID for all titleholders.
All keys and remotes
You don't need these things to get an offer for your car, but if you think you might sell when you get your offer, come prepared with these items.
