It looks like a late 70s/early 80s model. One step above the lowest model, the Sport. The asking price is about $20 more than when it was new. Steel rims, nutted hubs.
Is is worth it? Depends what you want to do with it, and if it fits. It looks like it's in great shape. It would make a nice campus/short distance commuter bike, but not a fast, sporty road bike for longer rides, IMO.
