Yes it is. Nice work. Though it seems to have turned into a Vette vs. GTO free for all.
I can't knock the latest gen GTO too much. The styling is way too conservative IMO. The interior is beautiful and the drivetrain, etc. is solid as a rock. Had they made the 2005-2006 in a vert, I would have most likely bought one.

As for the battle between a newer GTO and a SRT6 - I haven't had the opportunity to run one, but I'll keep my eye out. If only for Sh*&s and Giggles. I'd be interested to see how close they are.
