I purchased a 2005 BMW X5 for $14,000 on May 13 from an used car dealership. I put $7500 down and financed the difference. The dealer agreed to fix the navigation system which runs the navigation, radio, and every other system in the vehicle. I has been almost 30 days and he has not fixed the problem yet. He has consistently given me an excuse and the problem is still not resolved. I told him that I would like to reverse this transaction because he has not fixed the problem. He has refused and stated he will fix it. It is almost 30 days and I would like to know what are my rights in this situation.
