Solid riding bike, but only one or two steps above entry level. Not much value as a complete bike in today's market (ie: the cost of a rehab before selling would put you upside down value wise).
I'd strip it for parts, toss the frame. The parts are solid, if not exciting, and would be great for using on a "daily rider/not afraid to lock it to a bike rack" quality build on a frame more suited to your size.
