Need some direction with my Mom's 64 Dart

Getting back to your main question. This is your mom's old Dart. If you come into some $$ down the road, are you going to be able find this Dart to fix up if you send her down the road now? How much @ month to keep her while you do what you can? I get attached to cars, and don't like to send them down the road even without this much sentimental value, but you have to make this decision.
