I've never come across a car that is fun to drive each and every time you press the "start/stop" button! The X35D turbo is a rocket on the highway. If the highway is empty and I'm just craving a little get-pushed-in-your-seat-on-take- off fun, I just release the hounds. The 3.0 gas is not bad, but the 3.5D is just plain amazing. Interior technology is great. The backseat is actually spacious like a sedan and not like most SUV's where it's a bit narrower with no thigh support. The engine is of course a bit louder but the roar when you giddy up is fun.
Twin Turbo, Seamless Idrive-Ipod integration, most comfortable SUV seats ever, Google Maps integration with BMW Assist.
Need to figure out a better design for the running boards - they look good but seem to get in the way a bit when getting in and out (might be my fault since I'm not that tall)
