SVJCCIM,
You've come to the right place.
We love our cars and most of us are sanguine about what the market says. Depending on its true condition and/or hidden defects, your car could be worth $5000 or $50,000. But it's priceless for its coolness, magnetic beauty, and the joy it brings. Spend some hours looking through the threads on this forum and you will find all the items for your evaluation checklist. Then decide, based on what you find other owners have or have not done, whether you want modern creature comforts or absolute originality.
Practically speaking, first I'd look for rust...
