 Inspired by the sophisticated engineering and body development of the Italian Abarths, Unger produced sketches for a car meant to combine the admirable qualities of the Abarths with the excellent vehicle dynamics of the best contemporary British sportscars.During the car's gestation, Unger moved from Rootes to Ford, where he was involved in development of the Ford Cortina.At Goodwood in 1963 Unger and Valerian Dare-Bryan talked about their shared views on car design.
