All interior CF parts including the BMW factory sets are manufactured for looks.... I would agree with your first statement, but CF interior and exterior styling parts are being offered by all top-end manufacturers. I recently saw a new M3 at the dealership with CF interior and black matte vinyl wrap for the exterior on the showroom floor. Looked amazing!
