Actually if York gets his way Hummer goes by by as well.
I think GM will re organize into three "brands"

Saturn will sell the base cars.
Chevy will sell the base trucks.
Buick will sell the midlevel stuff. (cars, and SUV's)
Caddy will get the high end.

GMC will probably be carried over as well to sell up market Chevy trucks.

Hummer is pointless and when gas prices rise will not be profitable anymore. The writing is on the wall with that brand.

Saab is a useless husk of what it used to be, chop. Pontiac is pointless at this point as well.
