I liked the color of the valances in my 05 Diplomat, but hated the Day/Night shades. I replaced them with MCD's. They are very easy in a Diplomat, because the valances are so deep. If I didn't like my valance colors, I would recover them. Everyone's tastes are different, but I would be afraid that removing the valances and replacing them with curtains would make a newer coach look dated.
