71 Twister up for adoption

I bought my 71 Twister when I was 19 and it has remained a part of my family. However - I just got a $31K estimate for a “paint job”. Also - I may be losing my covered parking spot soon and I don’t want to go back to storing my car under a cover. The engine is running well but I have a long list of things that need repair or replacement (tires, instrument cluster, insulation, etc). I have the original sales receipt and stamp sheet to show that components are original. Is a 1 owner car in need of restoration worth any more than the other project cars out there? Please advise.

Looks like a nice one. One owner cars have more value if they are in nice shape. (looks like your's is) Remember before you or anyone else paints that, they are only original once.
