The S21 Deluxe-based Skyline Sport featured hand-built Michelotti bodies in stylish coupe and convertible versions. These cars used the 1.9 L "GB-4" engine from the S21D. While only a few hundred were built, Prince Motors had a very aggressive product placement group and they can be seen (along the company's mainstream models) in many Toho films of the early 1960s. The canted headlights reflected a similar appearance on the late 1950s through early 1960s Lincoln Continental, Buick, and Chrysler 300. The appearance is similar to the 1960s Lancia Flavia and Triumph Vitesse as Michelotti did contribute to Lancia vehicles during this time; Giugiaro's design of the short-lived Gordon Keeble GT was similarly influenced. Being the first sports-focused model, the Skyline Sport foreshadowed the Skyline GT-R sub-range.
