I'm still searching for a x5. I want a 4.4 with the cold weather package in blue, silver or white. So hence the long search.

My concern is it seems like the cost of owning a 4.4 is quite substantial over the 3.0 (plus I keep finding 3.0's all over the place). Seems like things tend to break a lot more on the 4.4 and most of the tranny complaints come from 4.4 owners.
My other concern in the performance of the 3.0 going up i-70 for ski trips, mountain bikinkg etc.. Any experienced feedback would be great. Thx.
