Douglas DC-3 and Volkswagen Beetle Type 1.
Both fantastically succesful designs from the 1930's and both are still widely being used today. You gotta love 'em.
The first we have in AH as the C-47, the second not yet, but maybe HTC will add a Kubelwagen or beter still a Schwimmwagen! Sweet.
For those not in the know, the Kubelwagen (German for bucket car) was the German equivalent of the US Jeep and it was Beetle based. The Schwimmwagen (German for swimming car) was similar but it has four wheel drive and amphibious capability! Even ordinary Beetles have been built as 4x4's in the war.
