FWIW: 2008 EPA mileage rating comparison
BMW 335i w/steptronic: 18 city/26 highway/21 composite
Pontiac G8: 15 city/24 highway/18 composite
Keep in mind, too, that the G8 will run fine on 87; BMW requires minimum 91 octane. I calculated a cost comparison and, using the composite numbers and regular/premium price difference, the G8 would be about 10% more per mile for gas. I usually get around 25 mpg in my 335i, but it's mostly rural/interstate highway driving. I doubt I could match that in a G8 GT. But the 335i is also much more cramped inside; you're obviously trading space for efficiency here (among other things).

imo, the cache of the 3 series has long worn out...just too many around. now the g8 gt on the other hand...i have yet to see one on the road, and by most accounts, it's a damn fine car! with my limited resources...a g8 gt will work exceedingly well, even if it doesn't quite rate up there (objectively or subjectively) with a bmw.

Are we forgetting the 1998-2005ish 3 and 5 series that had poor electronics and diodes in their dash panels?
As we've all been saying the G8 is not a BMW, however, for $30k you can't get close in terms of SIZE + PERFORMANCE from anything from BMW.

Cache, schmache. I would love to have one because they are the best performing and handling 4 seat car on Earth under $50k. Unfortunately, by budget is missing quite a few of those "K's"....

The one I lease has me spoiled. The base G8 is a houseboat in the suspension department (and roominess) compared to the 330. I will test the GT when my dealer is allowed to get one again!

There are so many things wrong with your comparisons of the G8 vs. 330; it's not even the same size for cryin' out loud. Compare it where it should be, 535/550; the G8 already beats it in roominess - which I desperately need. Comparing it to the 330 is a waste of time. I have considered the CTS 3.6L 6MT, but if I can get more space and performance for my dollar, guess where I'm going? Under the radar is the Hyundai Genesis... I'm waiting for it to show up so I can make my decision!

I know it's not an apples to apples but the difference in handling is huge. I compare what I consider for my next ride against old. The base G8 is out. On to the GT.

You realize that the base and GT suspension is identical. Only difference is if you buy the sport package that upgrades to 19-inch rubber.
BTW, if you check interior dimensions, the G8 is actually very close to 7-series BMW.

The 19" rubber does nothing to help handling IMHO. GT interior looks bigger than the 7-series to me. This is a great performance family sedan but a curve-carver it ain't.
There are just so many more opportunities to have fun with a serious sports suspension.

I understand what you're saying. Based on everything I've read, they considered a "base" suspension that was softer and a optional "sport" suspension that would upgrade to what they, in the end, made the standard suspension, which I believe is the mid-level Holden-spec suspension. The Commodore SS-V, I believe, has stiffer suspension specs than what we got on the G8. Let's face it, everything's a compromise. I think that, based on my test drive, they did a pretty good job. You can't make all the people happy all the time...
