Not bashing the GT...but if I had to choose (which I guess I did) between the GT and a GC, I'd choose the GC every time. The rear seat room is 6" less in the GC..but my 6' 210lb son seems to fit ok if the front seat is pulled up a bit. It's still tighter in front with the sunroof as well compared to his mom's 335 but he isn't paying for the car
. I don't come close to using up the 46cu ft of space (seats down)...so the extra 10cf in the GT is lost on my use.
