Also, I find parting out of the good older cars to be a saddening thing. Sure, it circulates a number of in-demand and useable/needed parts, but it takes that VIN off the road to not return and also reduces the ever shrinking population of interesting older cars driving around out there. It's nice to see the nice looking older cars on the road, it is industrial art - this is gone from modern production for many years. From what you describe it seems like your car can be put on the road again, for some $$$$, but perhaps reasonable amount. Only you can decide and only have the right to decide. For these reasons though it seems sad to me to see good cars become parted out, or very good cars become garage queens and never be driven on the road again because the owner thinks they're too valuable to drive around. In both cases it takes them off the road. They are meant to drive and be fixed and drive some more.
Best of luck whatever you do.
