Dennis, himself, started his career as an engineering apprentice at the Austin factory in Longbridge, spending his spare time building Cooper and Cooper S versions of the famous mini.  In the intervening period, in addition to rallying, he has worked in most disciplines of motorsport, including the British Touring Car Championship, Metro Turbo Challenge, the Rover ‘Tomcat' Series and single-seater racing.

In addition to the construction of complete cars, Dennis has also made a name for himself with the preparation of transmissions - gearboxes and axles - both for rallying and racing.  ‘Osborne Transmissions' are well respected and much used in the sport today, both by ‘works' and private teams alike.
