General Motors President of North America Mark Reuss talked to me at the 2011 North American International Auto show (NAIAS) in Detroit, MI.

What is the difference between retail and commercial sales? Do companies make more money on retail or fleet sales?

What about residual value?

General Motors cars have a 90 days supply, when the average is 60. Does that mean more incentives to sell those cars?

How did sales for the four brands left at General Motors compare to the eight brands they used to own?
