I found a great story on car salesmen at edmunds.com. One of its writers went undercover and worked at two dealerships. The insights that he provides are very informative. He actually lets you feel what it is like to work at a car dealership.
Here is a small sample:
"What the customer didn't realize was that the poor car salesman or woman was not really the enemy. The real enemy was the manager sitting in the sales tower cracking the whip. Suppose for a moment a customer told us they were "only looking," and we said, "fine, take your time," and went back into the sales tower. Now we find ourselves looking up into the steely eyes of the sales manager."
