Hi, I've got a 2006 Enduro Expert which is pretty much the same as the bike you are looking at. They're fantastic bikes, the best bike I;ve ever owned or even ridden, and I've had some pretty tasty mtbs. Things to watch for other that what has already been said would be make sure the shock is not 'stuck down', and either way even if the bike hasn't been ridden much I'd still seen both the forks and shock to mojo for a service as the bike will feel so much better if you do this. Haggle the price down using this as leverage and you'll be onto a winner!
cheers, Joss
