Jack Neill, sometimes referred to as John, was a garage owner from Swansea and was one of the first owners of a Kieft Mk I. His company, the Terminus Garage, became an agent for Kieft Cars. The Mk I was not particularly competitive and Jack struggled to get results though he did manage a second at Lydstep in August 1952 and was part of the driving team, along with Stirling Moss and Ken Gregory who set 13 records at Montlhéry in November 1950 using Jack's car.
Jack continued to test and drive for the company on an occasional basis.
