I'd like to know the good bad and ugly about this sled. I found one and buddys asking over 2500$. It has a "refreshed motor" ( new crank seals, all new gaskets, water pump bearings and shaft, brand new pistons rings and wrist pin bearings, v force reeds, drive bearings done same time as motor). Is it still worth 2500$+? I cant justify spending that much on a 21 year old sled.
