If the car came with with one and all the trim is there I go back with vinyl, I like the look. But if a PO has removed everything and went with paint, I leave it that way. When our cars were new , and then got to be clunkers, most sat out in the weather much or all its life. And of course , rot to whatever degree set in. But, chances are if you spend the time, effort, and money to restore/restomod one , it prolly won't be left out in the weather much. Do we really ever own a car, or are we just its current caretaker for a while...
