Mine has sport package with 20" wheels, but no adaptive drive. Honestly, i have never driven one with the adaptive drive, but I dont feel like i am missing much. I drive pretty agressive, even the X5, but i dont feel it is leaning that much. And once i got rid of the RFT the ride became comfortable without being plush. With these oversized tires i can out-turn 90% of the cars on the road.
Having to replace both front adaptive shocks on my wife's 2009 Z4 makes me a bit more happy about not having the adaptive drive. But what i really miss on mine is the HUD and especially the SLS, for my towing needs.
