Looks like you're coming from a 2015 M6. Cannot comment much about reliability; I've only had my X5M for about 1 yr, but no issues. I have a '16 X5M with 27,100 miles at this point. Warranty expires Oct 2019. I thought I was going to miss my M6 GC but haven't looked back since trading it in for the X5M.
I recommend having an independent shop perform pre-purchase inspection though.
Good luck!
