New Guy!

Hello I am not to sure what to put in here. But I am a prospective RZR buyer and looking to learn the tips and tricks to ownership. and hopefully find advice on buying a used RZR!
Ive got my eyes on a 2012 800s with 750 miles.
I dont have a clue really what to look for when buying a used RZR. do they have any common issues? specific wear points?
and most importantly is there anything that i can see/hear/feel when loking at a used RZR that should worry me or be a reason not to buy?
750 miles seems low enough that it could have been abused pretty good but not be "to late" to buy it and not expect major issues?
