KBB Old Car Guide would probably be a good guage to estimate a good starting price... (its availble at the local book store)

if this model is considered a 'special interest car', there is a guide known as Cars of Particular Interest (CPI) that also poses market values

...unless its a show-car or show-car qualty (as-new & fully maintained car w/ new hoses, etc.) I'd imagine that $4500 is more than fair due to of the age of the vehicle and liklihood of items requiring freshening
