You are able to obtain an offer on your vehicle as long as it meets the eligibility criteria in effect when you elect to receive an offer. However, if you owe more on your car than what it’s worth (negative equity), CarMax will calculate the difference between your payoff and its offer to you, and you can pay that amount to CarMax directly. CarMax stores accept cashier’s checks, certified checks, other types of certified funds, cash and debit cards. In addition, if the amount you owe is less than $250, CarMax will accept a personal check. CarMax Car Buying Centers (locations that only buy cars) can accept cashier’s checks, certified checks and other types of certified funds. Your offer is good for seven days, giving you time to get any necessary funds to settle your transaction. Learn more
