It's really hard say because we haven't seen everything from them yet. I'm on the fence with the looks of the C7 still. I'm waiting to see some owners get ahold of them and start modifying them with different wheels and such.
The new Z28 is going to be awesome and looks MUCH better now.
The new Stang looks very promising and of course has a HUGE aftermarket for it so the potential for it is unlimited.
We still haven't seen much in regards to the GT500/Cobra for the S550 platform so no telling where that will go.
One thing is for certain with all of this horsepower war stuff going on, it's good for all of us car peeps!
