Zedder, if the car has the original engine and paperwork, that's in the ballpark. You don't want to have to do lots of correcting little things at that price. Someone had a nice Bloomington Survivor '67 390 maroon coupe for sale for about six months at 79K, it was in the for sale section at Bloomington this year. Original engine and paperwork. I saw it and loved it, I'm not sure why it has not sold, but this should help you with the value of the one you're looking at. A/C adds some value, but certified Survivor in all four areas helps the maroon one.
Color on the one you're looking at helps. Red and blue increased the price as does black (I'm sure it's not black). Good luck and make sure the engine is not a restamp.
