built in 1951, this strange result of bodywork is part 1949 Cadillac, part 1932 Stutz, and part 1951 Studebaker

Elwood Needy was inspired by the debut of the 1949 Jaguar XK120, and purchased a 1932 Stutz as the donor car, shortening the chassis to match the legendary Super Bearcat. 

 While the idea was to channel as much of the Jag’s aesthetics as possible, a 1949 Cadillac Series 61 formed the backbone of the roadster’s coachwork. With the assistance of an aircraft craftsman, full wooden bucks were built for the stunning rear sections of the body, an elegance contrasted by the 1951 Studebaker up front.

Needy died in 1952, leaving the car unfinished. His son took up the mantle and had the car running and mostly completed soon after, only selling the car in 1963 to another enthusiast, who retained and enjoyed the car until around a decade ago
