I find myself ogling over G8 GT's on the few rare occasions when I see them, I cant say the same thing about V6 5th gens as they are everywhere especially once the rent a car place got a whole fleet of them and have become played out in my area of California.
I would personally go for it and never look back especially with all of the torque the G8 has that your V6 Camaro will never be able to duplicate.
