Well the sled in question is a 1999 MXZ 670 H.O. in very good condition, stock engine, one owner, 2,300 miles, clutched, upgraded rear springs, good track, 194 studs, upgraded skis, $2,000 obo. Now to me $2,000 seems a bit high for this sled but i need some input from others. Do you think its worth it? I owned a 97 mxz 670 last year and it was fun while it lasted (bottom end went-crank bearings?) I like the power of the 670, im not sure how reliable they actually are because the one i owned was beat to hell, but im guessing its like anything else, if you keep up on the maintenance, things will last. Well let me know what you guys think...??
