I stumbled across a really good article on edmunds.com yesterday. It's written by a journalist who was sent by Edmunds.com to go undercover and work for a couple car dealerships, to see what it's like "on the inside." He worked at a high-volume, high-pressure place for a month, the kind of place you think of when you think of slimy, slicky-boy car salesmen (and I use that term because almost all the sales force at that place were men). Then he went to a smaller, no-haggle place. It's a really good read, and you can find it right here.
