I'd take the used ones if they are as good as they look. I've not heard good things about any but the ones from JBG that say they come from Ford tooling. But I don't know specifically about the Coverlay door panels. However, I do know that Coverlay's recent dash covers are much better than their previous ones, so maybe they have stepped up their game.
