The best thing you can do is test drive the six. Forum bantering regarding the auto and if it is a good performance granny wont sway you. The six handles well, has a ton of power, and if you tune, pulley and CAI you can have a sub 12 second car. You seem to have a grasp of the GTO. Do yourself the favor of the test drive and let us know how it went.

Being a former owner of a NA and owning a 6 its a night and day difference so defiantly drive a 6. Plus you get a great forum full of great people and very very very rarely do you see hateful or disrespectful comments on the forums.
