Ok, a friend of a friend has an 05 F6 efi ext with the 144" track on it. I has under 700 miles, he just wants to get out of snowmobiling. Hes asking $5300 for it. Is this a deal that I should jump all over and not look back, or are there issues with these sleds. I notice that they were only made for one year, is there a bad reason for this or did Cat just decied not to make them anymore? Any input would be helpful. Them main reason that I am hesitant is that we haven't had any snow for the last couple years to ride on.
