Picking up a new 2015 RZR 570 from a person who won in a raffle. Basic white lightning. Paying $7500, what do you think. Only problem is no warranty, no miles on it but it was purchased directly from Polaris by the organization that raffled it off in March 2015, got awarded to owner in October and warranty had already expired. Called Polaris, nothing they can do. Any concerns I should have? Thanks
