I'm aware of five , and possibly six , of them . Harry Humberstone built the first of them for Alan to drive . It had a weird wood/composite monocoque , and utilised March 803 ( I think ) suspension . Engines were either 8 or 16 valve air-cooled Suzuki bike engines . This car was responsible for the funniest incident I ever saw at a race circuit , in the padock at Thruxton .

Ben Bowlby , who I last heard of as a designer at Lola , built one with his father Richard . This was a very successful car , and used a 1 litre Kawasaki bike engine .

Finally , I drew up plans for a mid-engined Imp-powered car using Ralt RT1 corners . I built one myself for Rob Mason to drive , which I never completed for reasons I don't intend to go into in this forum . Rob built a second car for Irish racer David Hall , which used a 1220cc Carter Imp motor with a Coventry Climax FWH head . Finally , Richard Harris , for whom I built Imp motors , decided to replace his Maguire saloon Imp , and bought a home-built F4 car called a Cirrus from a monoposto racer called Ian Rowley . This had ( I think ) Chevron F3 suspension at one end , and March F3 suspension at the other . I adapted my original drawings to suit , and Richard and his right-hand man Bill constructed a third car in accordance with the cardboard templates I made for them . Later on , Richard rebodied this car as a Nissan 100SX silhouette , altered the monocoque by replacing the tubular engine frame with a full monoccoque , and fited a 2.0l 16v Vauxhall engine and Dallara F3 rear end . This was the car sold to the Mandersons .

As for the sixth car , I have a feeling that John Schneider's car was not the ex-Humberstone car , but a spaceframe car that John had made for him to his own specification . I think that confusion may have arisen because this car also used a Suzuki bike engine .
