The Davis Divan is a three-wheeled convertible built by the Davis Motorcar Company between 1947 and 1949. The brainchild of used-car salesman Glen Gordon "Gary" Davis, it was largely based upon "The Californian", a custom three-wheeled roadster built by future Indianapolis 500 racing car designer Frank Kurtis for Southern Californian millionaire and racer Joel Thorne. After building two prototypes in 1947, Davis embarked on an aggressive publicity and promotional campaign for the car, which included numerous magazine appearances, a lavish public unveiling at the Ambassador Hotel in Los Angeles, and a promotional trip across the United States.
