1999 skidoo mxz 500 with 670 motor, I bought two sleds and made one nice sled out of them. The 670 was rebuilt, from top to bottom including two crank bearings, pistons and seals, the sled only has 2500 miles give or take. They were sitting for the last 4 years. New belt, track is in good shape with 144 studs, seat does have a rip at the back which has duck tape on it, Also have the 97 skidoo mxz 670 donor sled that can also. 1800.00 for both or trade for a short box regular cab chevy or gmc, 4x4, auto, v8, and in decent shape.
