It depends on what they bring in your area. I live in the south and a atv like that but not as clean sells between $800-1200. without the snow plow of course. It is a nice looking atv. That is alot of snow.I would say it should be worth around $1500 or more. It also depends on if the buyer needs an atv right then or snow removed.

(Currently I don't own a Polaris but I work on them all the time and get to ride cutomers for test rides. Maybe soon I will be a Polaris owner.)
