I loved my 2007 X3 with 167,000 miles. The 2013 X3 handles much better but I am not sure it will last 100,000 miles.
Best of luck

Yeah, the N20 is in a lot a different BMWs. The oil line became a problem as well that I didn't mention because it was fixed, but I had that problem as well.
The vanos failures are pretty common to a few BMW engines, not just the n20. Good oil with frequent changes along with getting the turbo oil line recall done should postpone the vanos errors. It did for me.
