What do you think it's worth?

well any car is worth at least the price of scrap.
the headlight rings and taillights on 63-4 tend to stick out from the car making them easy to damage.
some models of our old mopars are less expensive to find needed parts for than other models. and the cost of parts, restoration, etc has nothing to do with the value if you decide to sell. best to find a model you like and find a complete car in the best condition you can.
