Get the xc6 if it's a 2000 with the ves. Yes i own one, but I'm not being biased. Is easily the best sled of the decade that isn't a triple. It will smoke much bigger sleds, I do it all the time. They ride great, handle awesome, are extremely fast, and get awesome mpg, and are ultra reliable.
Is the xc6 sharper in performance than a 2008 switchback 600? Because that switchback was real slow compared to my MM with 15 hp less.
