For GM, should they eliminate Pontiac, GMC, Buick, Saturn and rebrand their more profitable vehicles into Chevy? The foreign divisions like Opel and Holden would be merged into Chevy as well. What about Saab? Sell it or keep it? Hummer and Cadillac would not be touched. For Ford, simply eliminate Mercury and keep Lincoln. What to do with Mazda and Volvo? Same situation like Saab. Anything good, bad and/or ugly about this?
