1970 Dart Swinger 340 4-Speed FC7 Plum Crazy!! YUMMY!!!
If the car is fully documented, meaning the ownership history is well established and well documented, that car has a lot of potential.
I agree the interior is a fairly easy fix, and I'd dump the 4.56 rear gear too.
But this car looks good and is not a bad buy, assuming the car's authenticity can be proven.
$14,500 BIN for a straight, clean, not rusted, FC7 original presenting 1970 340 Swinger, 4 speed car..not bad at all!
