I know this is the E53 and not E83 forum, but just picked up a Silver/Black, 2006 X3, Auto with Sport Package, MSport, 102K, fully loaded except for PDC and NAV. Yes it is not the "manly" E53, but for my purposes, it fit the bill.
So far so good.. Obviously not the "monster" 4.8is that TMV picked up, but its much smaller cousin..

Pics will happen soon, then off to E83 land..
I will still frequent this forum as I still like the E53 platform and learned a lot about the platform from the good folks o'er here..
