What does the Pontaic G8 compete with?

[MX793]

actually somewhere on autoblog there's an entry reporting that the 6-speed will be available on the 6.0L GT model. I'm too lazy to search and link it right now

I believe you are alluding to this article:
http://www.autoblog.com/2008/06/20/lutz-09-pontiac-g8-gt-gets-optional-tremec-6-speed-stick/

Which was followed a few days later by this correction:
http://www.autoblog.com/2008/06/24/correction-pontiac-g8-gt-will-not-have-an-optional-6-speed-stic/

So in a nut shell, no stick shift for G8s other than the GXP.

ah dammit

leave it to GM to clusterfuck a brilliant idea
