I am looking for some info on the 500 xc sp edge. I have been a die hard ski-doo rider for years but I think it's time for a change. I am thinking of ordering a new 500 xc edge or trying to find a used one(preferably with an M-10). I'm just wondering how people like this sled and are there any problems I should look for(i.e. engine failure, part failure etc.). My mind hasn't been made up yet on this sled but I sure don't like the direction ski-doo is heading. Any help would be great.
