Glad to see you got the Servotronic and Premium Sound. The sound system has 10 speakers. Mid's and tweeters in the front and rear doors (8 speakers total) and 2 subs under the front seats. Plus upgraded amplifiers. I like mine just fine. Much better than standard. There are also adjustable equalizer settings for the stereo available on the Nav system screen (something I didn't know when I got my '05, and I didn't get Nav!)
Servotronic steering is great. It's road speed controlled instead of engine speed controlled. It has a much better feel at higher speeds but is still very comfortable and easy in the parking lot.
Hope you enjoy your new X3 as much as I do mine!
