Bought a 99 Ford F-250 from a dealership. Upon initiation of contract, we questioned the current registration, and that it was due at the end of the month we purchased the truck. We were advised verbally that this was handled and the registration was taken care of already. We signed the disclosure advising that estimated registration may come in at a higher price that estimated. We were advise verbally that this was not applicable to our purchase since the registration has been paid. 3 days after purchasing our vehicle the contract salesman called our home to advise us he made a mistake on our registation advise and we needed to either bring in our current contract to be re-written with the addt'l registration applied so that we can pay along with our payments or bring in a check to cover the difference. This is a substantial difference from $54.00 for transfer fees to $605.00 needed additionally. This man was sorry he had to do this. His reply to my statement "When we inquired about the registration, You said this was handled" (not once, but twice we inquired about this prior to signing the contract and his answer was "No problem, it's handled". Where do we stand with this problem? I feel they made a mistake on an assumption and did not confirm until 3 days later. I feel that this mis-representation should nullify the signed disclosure of estimated registration fees. We have received our registration tags, as the dealership paid these fees as the contract states. Is this legal? Do I have any rights with regards to this fast one they have seemed to pull? Please advise at your earliest convenience. Thanking you in advance for your assistance.
