2008 rzr 800 vs 2015 570

Hello everyone, I am new to this forum and I am looking for opinions or pros vs cons on the 2008 rzr 800 vs 2015 570 rzr. I was originally looking for a used razr in very good condition so that I can pay cash and not worry with a payment plan. I looked around for a while but couldn’t find anything used in great condition which led me to consider purchasing a new rzr 570. Now I have found a 2008 rzr 800 with 51 hours 5xx miles in excellent condition for a bit less than 7k. Should I buy this or spend $9500 before extended warranty on a base model 2015 570? I would appreciate any opinions on this. Thanks. Also, the 800 already has some accessories.
