I recently purchased a 2011 35d and absolutely love it. When I was first looking at X5s I was planning on getting a 48i but that quickly changed once I realized the issues with the 48i and the fact that I could have plenty of power and features if I just spent a little more for a LCI diesel. Extremely happy with my purchase so far after about 500 miles of ownership. Oh and the CIC is light years better than CCC iDrive.
