An extremely charming British Classic and engineering marvel that lives up to its "Jupiter" name. The Jupiter achieved competition success with a record-breaking class win at the 1950 Le Mans 24 Hour race, a class 1-2 in the 1951 Monte Carlo International Rally, an outright win in the 1951 Lisbon International Rally, and a class 1-2 in a gruelling 4-hr sports car race on the public road circuit at Dundrod in Northern Ireland in September 1951. This was a resurrection of the famous Ulster Tourist Trophy Race of 1928-1936 previously run on the 13.7-mile (22.0 km) Ards circuit. Le Mans was again class-win in 1951 and 1952, and lesser events were taken in 1952. This particular example was owned by its previous owner for 40 years and has been looked after by Jowett specialist Dennis Sparrow. He rebuilt the engine to a standard where it is producing 80hp +.
