Those dinky add-ons don't justify that price tag. I'd bet you that I could take the base model 2012 XP and make a better sled that the 2013 XM. From the skid to the skis, for less.
Yeah that might be possible, but you should try riding the 2013 first before you claim that the price isn't worth it. I have had a tone of feed back from people that have been rippin on the 13 and the general feeling that comes back is bring your check book cuz your gona want one really bad!! All I'm sayin is try it before you knock it...
