Inherited 1967 Dodge Dart Slant Six - help welcomed!

I think it would be worth quite a bit to you and your Dad...but a 4 door /6 car is never going to be worth a lot...maybe 2K-3k. I fixed up a really low mileage Texas 318 4 door dart with AC...etc...put disk brakes on it..cop wheels..8 1/4 rearend..really clean car. I did get 3500.00 for it.
Bottom line it cost as much to fix up a 4 door car as a 2 door car...2 doors will always be worth more than the 4 door. Though the 4 doors are usually in better condition....now if you convert it to a 2 door post car...:) Then you'd have something.
