There -is- something to be said, however... about going all out and getting "CF" fenders, hood, decklid, spoiler, and grille. I do believe that at one time there were some fenders in the making. However, the cost offset the benefit by a seemingly wide margin. It's just not worth it to most of us.
edit: i'd still have to paint it all as i do not wish for my car to look like many miniature chessboards patchworked together
