My saga sled is a 2002 and Austins is a 2004.  There are some major differeneces in chassis design and overall weight differences, same power but the newer the better as sled technology rapidly advances. Ok my sled is a P.O.S. Austin sold his sled to Windells so you can see it still making laps with the Diggers up at Mt. Hood.
