A 1958 Jaguar XK 150 S 3.4 Roadster, originally finished in Carmen Red and distributed to Jaguar Cars New York, believed to be among roughly 200 factory-fitted close-ratio gearbox examples. Following a five-year comprehensive restoration completed in 1997 by Olde York Classics, the car was refinished in British Racing Green with a biscuit leather interior. It subsequently dominated concours competition, earning over 82 awards including five consecutive perfect scores at JCNA National Concours Championships between 2009 and 2013.
