Yup Dragon, as Rye said, a vendors worst nightmare is an informed customer. Did you happen to go to Alexander Toyota?
When I worked there I knew 10x more about the cars in the used-lot than the salesmen themselves. I jokingly asked "So, if I traded in my Corolla, how much would you guys give me?"
"Oh, probably about $500."
I laughed at the guy so hard then told him if we put the car at the front of the lot as if it were for sale, it would sell days ahead of any car he would pick out already on the lot. Didn't believe me of course, but eh, never got around to proving him wrong.
