Just to add a little more information -
After production of the Gordon-Keeble car ceased in 1967 in Southampton, Jim Keeble went on to be involved in many different engineering projects.
In the 1980s he designed and started to build a space-framed high performance three-wheeler capable of 125 mph but, due to illness he was unable to complete it. He sadly passed away in 2003.
The K-3 was bequeathed to the Hampshire Industrial & Social History Museum 'Milestones' in Basingstoke, Hampshire.
Jim's great friend Derek Baker eventually completed the car.
