The cars were almost solely designed, engineered and constructed by Brian Shead in a small factory at the rear of his home in Mordialloc, a suburb of Melbourne, Australia.
A completely new design was commenced in 1970, after which a friend (Don Biggar) persuaded Shead to construct an additional car, Mk4H Hill-climb car powered by an Oldsmobile V8 engine.
By 1973 Shead gave up his usual job to design and build race cars full-time.
Cheetah race cars are common sights at Australian historic race meetings, hill climbs, sprints and in Australian Formula 2 and Formula-R.
In the latter two categories, Cheetah Mk7 and Mk8s which were built in the late 1970s and early 1980s are still winning races and championships against far newer carbon fibre tubbed Dallara and Reynard Motorsport cars.
