1946 Nash "600" Advertisement, "The Coming Thing in Cars Has Come!"

Nash introduced its 600 model for 1941. It featured unit-body construction with the frame and body built as an integral unit. The technique improved handling and stability, and it reduced weight. Nash advertised fuel economy as high as 30 miles per gallon which, with a 20-gallon tank, was enough for 600 miles of range -- the source of the model's name.
