need advise on my 4door. worth keeping or part it out.

I think it depends on what you like. These days there is nothing wrong with restoring an old 4 door if you like that type of car. We are seeing more and more 4 door cars showing up at the shows as the supply of restorable 2 door cars dries up. In general a like, built 2 door will always be worth more but you can still have fun with a 4 door. This Valiant was at this spring's big show in Myrtle Beach. A real beauty inside and out. The red 62' is my money pit.
