Looking at upgrading to XP900

Hello rzr fellowship I currently have a 2012 800s that I’ve just did the pinion nut repair trick to and have been thinking about a different rzr

After reading around the forum it seems like the XP900 has the lease amount of buggy problems so I’ve started looking for one of these machine’s to replace my 800s

75% of my riding is dirt roads and logging trails with a ride into town twice a week 25 miles round trip the rest is driving in heavy woods and swampy areas

What should I be looking for (problems) when I look at a used XP900 I’m looking at basic machines without alot of upgrades "I would rather do upgrades myself" I prefer the fox 2.0 shocks and I think a model years of 2013-2015 also I really like the 60" wheel base compared to 50" and a 2 seater only

This will probably be the last rzr I’ll ever buy since I’m 69 yr old now so I want a machine that will last the rest of my life

Any advice about these rzr will help me choose my next rzr ??
