original color or change
There is a 69 440 dart with bronze paint, black vinyl top, black interior and black stripe, LOOKS GREAT
if the rest of the car looks as good as the dog house, clean it up and leave it alone.
Original cars are hard to come by, and by far worth more money if clean. But if it needs restore, value will be higher painted back original.
If you want a blue car, flip this so someone can have a nice original in a great color
