If your riding the mountains I would look for a 02 or 03 polaris Rmk 700 or 800 long track. At least a 144 if not 151 or 56. MHO. I would think you could find one of those in the same price range...
biiig difference between a 700 pro x and a 700 classic... very good deal for the pro x...and talk him down a little for the classic...find out which one it is
