Forgive me if I respectfully disagree - that GTO mockup looks hideous, I've always thought so. I still have an 04 and it looks miles better than that Transformer-wannabe atrocity.
I still say GM has enough room for 2 RWD sporty cars - meaning the GTO AND the Firebird, an idea they seem so incredibly deathly afraid of. They've got a chance to really do something great here, time will tell if they piss it away that chance or not (not holding my breath...)
