The original KDF-wagen as it was called was basic and rudimentary, but essentially the same as the later post war production cars that followed. Features of this vehicle included cable operated brakes (!!) and a tiny 800cc flat four motor with a single exhaust, 16 inch tires and the KDF twin glove compartment (without lids) dash.Oh, and last but not least – probably the most famous and sought-after rear window in automotive history!
