Incentives and the warranty.It's true and low mileage too. Sadly, the selling prices aren't worth it when you can get a brand new Stinger for around the same amount with incentives etc. I've had several dealings with carmax in the past and have come to the conclusion that if you can't sell your car privately then they are the go to (if you are in a pinch). I try not to buy from them though as you can get better deals elsewhere.
