I just bought a 2003 Polaris 500 XCSP Edge X with electric start, reverse, M-10 ACE, 1 1/4 track, and it has 3,030 miles. It's in nice shape but needs a good cleaning, new battery, and the cover on the rear shock of the M-10 is worn badly. I got it for $2000 and was wondering if that was a fair price to pay because I bought it on a spure of the moment thing - the seller needed to move it because of money issues and it seemed like a good price. I'm also wondering if the cover on the rear shock is necessary because I've never had one on any other rear shock, but then I've never had an M10 before.
