Has anyone heard that a factory defect would make your bullitt worth more? I bought my bullitt 4148 in August and one side of the exhaust was a mustang GT and the other side was the bullitt. The dealership said to keep it that way because the car would be worth more. I didn't agree with it or the way it look, so I had it changed the right way. I just didn't trust the dealership with my car. Is there anybody else out there with any similar stories?
