Any reason to avoid 13/14 1000 XMRs?

I am in the market to buy 1 or 2 XMRs one for me and one for the GF, I am most likely going to buy a 2016 for me, but I’ve found some 13/14 1000’s for $9k-$10k and thinking of getting her one of those, any reason other than the ACS to avoid these? Do the 15 have that much more enhancements to look at those instead? I don’t want a machine that has to many idiosyncrasies as I want the machine to be as simple and reliable as the King Quad 750 she rides now.

If I got a 2nd new one I might get he a 650 or 850.
