Volkswagen's origin in USA. Germany, it was inspired by Hitler. First car was the beetle or bug designed by Porsche to meet requirement by Nazi party to produce a "peoples car" i.e. Volks Wagen - major production was sidelined by WW2 except for miltary variants. After the war, the British Army found the original factory and part complete cars which they finished off and used as staff cars - thus the modern Volkswagen cars were born. Porsche reused many components from the Beetle for his original 356 and several models of Porsche have used VW parts such as the 914 and 924.
