You should check all the old “classic” famous car exterior designs and which older non-famous designers were they stolen from.
e.g. original VW Kaefer supposedly designed and credited to Porsche. In fact… another Czechoslovak designer created the most of it but people only know about Porsche (who btw was also Czechoslovak ). https://en.wikipedia.org/wiki/Tatra_97
I guess it was just important to please Hitler and start a business that is currently respected in the whole world as a “standard for perfection”.
