AutoMoto.Tv has a great segment on the history on the Mercedes-Benz Special Vehicles production and the current S600 Pullman Guard. This is the latest in a long and unique tradition of large, armored, prestige limousines from the world’s oldest automaker. Mostly used by government leaders, dictators and other who fear for their life – which is probably not the best feeling in the world, but at least being driven in the luxury of the S600 might reduce your depression and the use of Prozac.
