A restoration of ANY car is a minimum of $30K and usually closer to $70K, even if it is a slant six car or worse, a Chivvy or Ferd! We did a slant six Dart GT convertible for an original owner 15 years ago and he had almost $75K in it when complete. No car is worth restoring for a profit, unless if course it is a Hemi car, then you will still not make much money. Those who think they can do it for less will have a car that will look like less, buy it an restore it if you like it, no if you are planning on making money.
