I'm not a big fan of the G5. It seems sort of generic to me. The cobalt, at least, has its own style. The G5 is like if a Cobalt and a G6 had a baby. A mutt, really.
I think GM'* frantic attempt at getting a cobalt-sized car had Pontiac basically make a cobalt with G6 lights.
And, correct me if i'm wrong, but it seems to me like the G5 should have the option for the supercharged or turbocharged engine, since Pontiac always had the more performance-oriented cars. A G5 GXP? Cool. [I use the term "cool," lightly]
