This was Jowett’s only sports car and was created by using Javelin mechanical bits in a tubular spaceframe. Though no beauty in the conventional sense, with its high nose and low tail, the body is at least distinctive and was created from a mixture of steel and aluminium panels. The whole front hinges upwards to give superb engine access. The MkIA from 1952 has a larger boot, with a bootlid this time. Three class wins at Le Mans and one in the Monte Carlo rally proved the Jupiter’s worth and attracted enthusiast buyers.
