re: Scammed by auto dealership...What should I do?

Talk to your bank/credit union about refinancing the loan. At 750 credit score, you shouldn't have a problem getting approved through them.

Also cancel the warranty if you don't want it, but I'll tell you that we took full advantage of the warranty on my wife's Escalade- replacing the shocks by themselves covered the cost of the warranty, then there was several other small things that the warranty took care of. It was definitely worth it for us.
