As a newbie to polaris, I don't know the differences between the two. What is lost when going to a value line product? Would one be better off spending a given amount on a late model used XP as opposed to a new 570? I know a guy locally that has a used Sportsmen XP maybe an 09 with a plow and some extras that was actually the wife's unit. Very low miles. They are going to a UTV. He says $5700 firm. It is the bigger 800 or whatever they were then. Thanks for any info/knowledge you can share.
