OK, so I am watching TV last night and actually watched the commercials. This idea came to mind:

What if GM were to limit the models offered by each segment?

Pontiac will be the "excitment" group. They would make the performance sedans and GTO's. No SUV's, minivans, or grocery getters.

Chevrolet will make the fleet vehicles, trucks, and midsize vehicles.
GMC would go away.

Saturn would make the SUV's, grocery getters, and eco friendly vehicles.

I'm sure I have missed some segment but I think you get the ideas. IMO, they have too many of the same vehicles, simply rebadged as something else.
I don't think this would save any jobs but it might be a place to start.

Before you all go and flame me, I too have a stake in what happens to GM as my company does the vending in most of the plants in MIchigan, Ohio and Indiana.

As far as Delphi goes, I don't know what would help them.
