For a non demo bike it's a steal.
For a demo bike, I dunno. I don't know much about fox's warranty, but fork damage would be my big concern. The steel frame is probably fine, but if the fork has been abused, things could turn very expensive. Same is true to a lesser extent for the drivetrain. Expect to replace chain and cassette soon. Basically, you're buying a used bike, but with a shop's support. So how much is that shop support worth to you?
