My neighbor has the Polaris SXS 800, but his has bucket seats and looks to be a nice rig.
Friend has the CanAm SxS and loves it. So that is my knowlege of either.
Me, I still have my 98 single jug 400 AT 4x4 Kawasaki Bayou with a manual shift gear box, really like it and will have until it or I die. (at my age there are mornings where think I know which will go first) Wife has a 2004 carbed 800 Polaris Sportsman with IS, auto 4 WD and she loves it, but compared to my 400, it is a gas hog.
