Sometime between 2000 & 2003, Specialized added a suspension fork and updated the frame geometry to accommodate. If the bike has a rigid front fork, it's older than that. If it has a suspension fork, it's newer. Either way, whether or not you're getting a deal at $100 is a matter of condition.
You can check out the Hardrock entry on BikePedia for more info. Click on the different model years until you find a bike whose parts match the one you're referring to.
