First I am not saying I don’t believe you. I am interested in hearing more of the details. Personally I don’t know if buying a demo unit makes a difference. A demo would infer that it had been driven 6,000 miles (in your case) and let’s say there were minor rock chips or a cracked windshield or even upholstery parts replaced maybe? Before passing judgement that anyone tried to defraud you i would need to know more.
How did you find out? Did you check CarFax? As far as different studios a demo unit could easily be in different studios. That wouldn’t be an issue.
