What are the tricks salespeople use to increase their profit and how can consumers protect themselves from overpaying?

These were the questions we, the editors at Edmunds.com, wanted to answer for our readers. But how could they really know that our information was accurate and up-to-date? Finally, we came up with the idea of hiring an investigative reporter to work in the industry and experience, firsthand, the life of a car salesman.

We hired Chandler Phillips, a veteran journalist, to go undercover by working at two new car dealerships in the Los Angeles area. First, he would work at a high-volume, high-pressure dealership selling Japanese cars. Then, he'd change over to a smaller car lot that sold domestic cars at "no haggle" prices.
