We have an e60 535xit for family hauling, but I expect to occasionally need to shepherd 1-2 kids. The f80 is the same size as my e39 m5 for all intents and purposes, so changing from my current ride to an f80 would basically be swapping for a 13 year newer model with all it's bells and whistles (albeit with a less plush interior).
My main concern is 2 hour drives and ride comfort, but it's not like I'm coming from some soft suspension'd system. I also simultaneously want tight and responsive steering, superb brakes, and instantaneous acceleration
