Confessions of a Car Salesman
It's a long read, but it's really well written. Edmunds hired a guy to go under cover to work at at 2 car dealerships. The idea was to get first hand knowledge of how the car sales industry works from the inside. He went to work at a high traffic, high pressure dealership and a slower "no hassle" dealership for a month each.
If you've ever bought a car, are thinking about it or just need something interesting to read, check this shit out. His tale starts with applying for a job at a Japanese car dealership in LA. High stakes, high pressure.
