How does the stock C6 stack up against a stock Z06 in terms of day to day driving?? I know the C6 is supposed to be a little stonger down low while the Z06 supposedly pulls harder up top, but is it really a noticeable difference?? Just curious as I was bored today and took a ride down to the Chevy dealer here in Pensacola to check them out (on a side note, those clowns are still charging 5Gs over sticker)
