The 1948 Davis Divan - An adaptation of the 1939 [Frank] Curtis, three-wheel ‘Californian’ roadster, by a group of talented engineers from the aerospace industry for the Davis Motor Company, Van Nuys, California. (bottom image via Show Me Fact)
The most unique feature of this 'car of the future’ was the built in jack for each of the 3 wheels - these were fabricated out of military surplus hydraulic cylinders and lifted the car by flipping the appropriate switch. Only eleven Davis Divan’s were produced - Davis Motor Co. came to an ignoble end when the company was seized and liquidated by the LA District Attorney’s office after Gary Davis was hit with fraud and other charges related to failures in meeting contractual agreements.
