Vintage Cars: worth, fixerupper, lt 1

Question
Have a 1980 Mazda RX7 500 miles an rebuild motor has some rust on rt/lt 1/4 panels needs TLC It is the anniversary addition any help would be nice Thanks Steve Do you know anyone who would want to buy ?

Answer
You can always start with KBB.com or similar.  Problem with vintage cars is that most people want a fixerupper or a refurbished ready to hit the road car.  Test the market and see what happens.  The 80 RX7 is a nice car, I use to drive one!
If you like it and can get it looking good for a few grand its far cheaper than a new one, or new car of any kind.  Good luck
