Dead pedals should be on all manuals, it's where your foot goes so that it is at the same level as the clutch pedal. It really is not needed on an auto as that left foot is not in play.
Max has made and fitted one and they are available I understand from Mercedes as a bolt on. Saying they are not needed on a manual is false as they are needed more.
