2017 Polaris sportsman 570

What does everyone think of the 570??? I can get a green or red 2017 for $5399. There is a small title and document fee, but I just can’t see paying $4,000-$5000 for a used machine with 500-1000+ miles when I can buy brand new with warranty for a few extra bills. I also have a chance to get a 570 with power steering. It’s a 2016 with 76 mi on it. Only issue is the guy says there is a loan on it, but he says he has a transferable registration which is what is issued for Atv’s in New York. So my question is, if I buy that machine, and he doesn’t pay the loan off, can anyone come after me because he didn’t pay?? Or will that be solely his problem to deal with? Both the new and used machine are 2.5-3hrs away. So I’m not worried about buying new from the dealer, I’m worried about the used one, paying for it, coming home and trying to register it and they say that there is a lien, or some kind of a red flag on their system not to allow it to be registered, then I’m screwed! Let me know what you guys think about the machine itself, the deals on them, and about the loan thing. Thanks!
