A salesman that judges a client by there cloths and what they drive is a very poor one. In my job at the boatyard during the summer I work with very success business owners regularly. They dress the part only half the time. I know someone like your friend blackmercedes, he is a very successful builder. He drives a 15 year old Caddy or the company trucks. He could easily walk in to a MB dealership and write a check for a couple, of whatever he wants. On the other hand I have had credit cards rejected from people that the MB salesman you described would be all over.
