First off, I have a 09 GT and freaking love it! They really should have made more of these cars...they should have brought more Holdens to the US...sad. Secondly, the only time "G6" and "G8" should be in the same sentence is when someone's referring to Pontiac cars. G6s are pieces of dog shit--when the G8 was released in 2008, it was the fastest car under $30k with 365hp at the crank. Stock, I had about 295 rwhp, after a few mods I'm @ 358rwhp and 370rwtq. My only big complaint right now is that there is a TON of alternator whine which I need to address. Other than that I really don't have any issues with a performance sedan with 50/50 weight distribution, runs a 13.5 1/4mi bone stock, and a 6.0 V8 that gets between 22-26mpgs on the highway...J-Sing
