I test drove a G8 GT yesterday. The car is way too quiet. The exhaust note says V-6, not V-8. I like the auto trans manual shift mode, center stack readout screen and seats. The interior seems a bit low grade in several spots, but I guess that's how you get a car with 361 hp to be under 30 large. Lots of tradeoffs. Wheels are also unremarkable. I actually like the V-6 model's wheels better, except they are smaller.
I'll wait for the GXP myself and hope the improvements seen on the show car come through in the production model.
