After he stopped driving, he became founder of the British Dealer Opel Team (DOT) as well as the self-willed but successful director of the Opel Motorsport Team in Germany, for which Walter Röhrl won the World Rally Championship for Drivers in 1982 with an Opel Ascona 400. Returning to England in the late 1980s, Fall formed the company Opel Classics, with Steve Thompson Cars (UK Irmscher Car Dealership) and Tom May (Director of Irmscher UK). The company became responsible for restoring and maintaining ex Opel competition cars and they also built a small number of fully re-commissioned classics Opels using the Opel GT model, cars being from California and also an Opel GT purchased by Fall from an Opel Dealership during the 1982 San Remo Rally. After this venture, Fall became first the manager and later the owner/director of the Safety Devices company. Fall's last major outing was the 2003 Historic Rally Championship with co-driver Jonathan Hall-Smith, where he competed with his Datsun 240Z.
