140k on mine. Fluid changes, brakes, tires.
Some stuff under warranty early on, otherwise fine.
Now, my 2010 (same E70 X5d) was lemoned due to emissions crap.
Just feels like they figured out a lot of it over time. But thats n=1. I certainly have read ALL the issues over the last 10 years here and on bimmerfest. (FWIW, ordered a 2009 and refused delivery, so Ive been looking at them since then...
