My former daily was a 2010 X5///M.
Loved it for awhile, then tired of the rough handling. Power was great, but lost on me as I really only drive the X in the rain, snow and/or with the family on-board.
I was considering a brand change, then drove the 50i with Adaptive Drive. Loved it... Much, much better ride IMO in both comfort and sport mode than my ///M, so I ordered this M sport/M Performance version. 8 speed trans is a nice improvement, as-are the comfort seats. No cheapo 'carbon leather' option, so I went bamboo. I'll post pics of the interior later.
The BMW cross rails are adequate, but whistle above 70mph. For me, not a big deal as they will be on the X maybe two times a year.
So far, I love it. I don't love the dealer hack trailer hitch install, but it's nice to have a hitch again.
