The underhood shots reveal what looks like some sort of a new wiring arrangement with relays on the passenger inner fender near the horn. Also near the master cylinder on the drivers inner fender - looks like a ballast setup. The cooling system is all aftermarket. The engine has all aftermarket dress up pieces for the valve covers, air cleaner, etc. The interior needs a full rework and that cage has got to go. Car may have lived a tough race life, twisting etc. Needs exhaust but no big deal.
Certainly if the rust is confined to the areas described, this is a very good deal. A buyer could drive this and decide whether to restore or leave as is.
