the 1920s Austin was really well built, engineered and designed, and was selling so well, that it was licensed/franchised and built and sold at BMW Nixi, Rosengart, and American Austin. Even Nissan copied it

in 1927 BWM introduced something new: the Dixi DA-1 3/15, a license-built copy of the Austin Seven.

Hard to imagine now, but the cute, fuddy-duddy little Austin Seven was, in fact, a revolution: small, cheap, yet well-built. It was England’s answer to the Ford Model T and it put the country to motoring with 375,000 built. Companies in France and Australia built it under license. In America, the aptly-named American Austin Car Company sold ’em with fun, cutesy big-car restyling, shrunken Stutzes and Marmons that looked truly cartoonish. Not only was the Dixi BMW’s first car but also Datsun’s, half a world away (though they may or may not have consulted with Austin before they started building it. The debate continues). By the 1950s, however, both companies had sorted it out.
