hay i have own 3-4 polaris 2 which were newer then a 01, and i sold all of them and still have my 01 xc. it has been the best sled i have every own. its fast, and you can do so much with them if you want to make them faster. Like clutching and twin pipes and reeds, it makes that sled run with the big boys trust me. if u want it run get with hot seat,HI I AM THINKING OF BUYING AN 01 600 IS THEIR ANYTHING THAT I SHOULD KNOW OR LOOK FOR IN THE SLED? WHAT CAN YOU TELL ABOUT THEM LIKE HOW ARE THEY ON GAS ,ANY PROBLEMS ECT.
