I'm looking at buying a Safari for ice fishing and there are two near by for sale. One is a 91 with a re-built motor and a bad track that has 10200 original km on it for 1000 canadian and the other is a 94 with 4720 km on it in original condition that looks almost new for 1350 canadian. Is there any major differences in these two sleds? Any upgrades from 91 to 94 that made them better? I just can't decide. Any help would be appreciated. Thanks and bring on the snow!
