[T'Cal]

I heard an anology about GM once that seems to apply exactly:
GM is so big that it is like an aircraft carrier at sea. When it needs to change direction, or turn around, it needs a lot of time to do so. Changes in direction come slowly.

GM will have to make some changes and I believe that trimming down the number of car lines would be the best place to start. Drop everything except Chevy (value & performance), Buick (near luxury), and Cadillac (luxury) and maybe I'm being a little too generous in keeping Buick.

As for the Kappa I, I agree with those who already posted that GM should do more with the platform. They should add models based on a longer wheelbase such as a Chevy Nomad two-door wagon and a Buick or Saturn four-door sedan. There really is no need for both the Solstice (silly name, BTW, altho I wouldn't want just an alpha-numeric name like the G2) and the Sky (also a silly name). Either differentiate them more (one a two-seater and the other a four-seater vert) or drop one completely but add the aforementioned wagon and sedan.
