I purchased my black crossfire auto at carmax in Orlando for $29,880. I bought the car the day before Thanksgiving. The car was advertised as a demo. I live in Sarasota and I asked them to hold the car until I arrived after work. When I arrived I asked them how many miles were on the car. The car only had 19 miles on it. Not exactly what I would call demo mileage.
They did not gouge me for anything. The only extra fee I paid for was a processing fee of $99. Perhaps dealers are allowed to sell cars as demos after a certain period of time.
By the way, mine has the new radio.
