Cars, incentives, and the end of the month

This story from This American Life is fantastic. It is an account of a car dealership that earns a sizable bonus if it sells 129 cars in the month. It raises or answers many questions:

1. Does the sales manager respond to incentives?
2. What are the personality traits of a successful salesperson?
3. When do car salespeople purchase cars for themselves?
4. What does the Art of War have to do with selling cars?
5. Do automobile manufacturers use the bonus scheme effectively?
6. Do buyers get good deals at the end of the month?
7. Does a U-form organization help all divisions work together effectively.
