Contract supersedes verbal promises

I went to a Hyundai dealership and signed papers that were at a higher interest rate than I was told verbally. I was told 6.15 percent and it was actually 14.67 percent. I called immediately once I realized this and was told it was binding. I understand this, but there was not a deposit, so can I get out of the deal?

Once you sign a contract -- no matter what the salesman says -- you have committed to a legal obligation. The contract supersedes anything that was said -- period. You can make noises about complaining about consumer fraud, but if the contract states in clear terms what the interest rate is to be, then the deal is done.
