If you have the time I would go to a few Chrylser Dealers and see if they would take the Crossfire upon arrival as a trade ; youn should at least get dealer's invoice out of the car. If you get registration etc. on the car you will also have sales tax to pay. If possible , find a dealer that will work with you on this. There has to be a way to save a few bucks and get the most in cash value out of the deal. Also check on the web (Kelly Blue Book and NADA prices) This will give you an idea of cash value for the Crossfire. Also Mastercard appears to be the sponsor and they have a say on how the prize is awarded. Try to negotiate a cash deal with them.
