I'm running into the same situation with my '00 Wagon. The door panels, as long as the rigid pieces are in good shape can be redone by cutting the old insert material out, removing the remaining glue from the plastic and gluing in new material. For mine I used a decent marine-grade vinyl that looks as good as the factory leather. The plastic parts are a little bit of a challenge because anything factory will have the "soft touch" coating either rubbed off or in very poor shape. Some have sanded the pieces down and painted them with a satin paint. I've been lucky enough to snag spare pieces from Craigslist when I needed them
