My mistake. Perhaps I should have said Chevy-Hater / Subaru-fanboi
Actually, I'm no fan of the Cobalt in particular. If your experience with them is such that you would never own a Chevy then that is understandable.
However... I think if "I" had my choice between a brand new Chevy Z06 and two new STi's, even with how much I love the new STi, I would take the Z06... Hands down.
