The F10 is huge compared to the E90.
Granted, the back seat isn't WORLDS bigger in terms of leg room, but then again, I'm 6'2" and sit WAY back. But in an E90, with the seat positioned for me, NO ONE could sit behind me. The seat was almost touching.
The GT (F07 by the way, the F11 is the wagon), isn't much bigger. And the trunk, while a hatch, isn't much more usable.
I have two kids (2.5 and 6), and we have done several 5 hour trips in the car in comfort.
