me too... personally, if someone I didnt know came into my shop and wanted to take out one of our cars that was for sale, if one was for sale (from our Gallardo down to our F350) I would not only go along for the ride but make a copy of their insurance and drivers licence (as well as a backup copy of ID probably).
As far as the "affluent look" that was directly from the managers mouth. I learned long ago not to judge a book by its cover. My father worked very hard and has become an expert in his field of law and dresses WAY down on the weekends, think jeans and t-shirts. Even going to buy my mother her new BMW the dealership didnt want to give him the time of day.
