Chauffeur (The Seeds of Doom)

Harrison Chase's chauffeur drove his 1970 Daimler limousine.

Biography
After the Fourth Doctor and Sarah Jane Smith returned from Antarctica, Richard Dunbar arranged for Chase's chauffeur to pick them up, take them out to a quiet place somewhere and kill them.

The chauffeur drove to a deserted quarry and pulled a gun on the pair. However, the Doctor surprised and knocked the chauffeur over when he and Sarah got out of the Daimler, enabling them to escape. The chauffeur gave chase on foot, but was ambushed and knocked unconscious by the Doctor after a brief fight.

Dunbar later told Chase that the chauffeur had been taken to a hospital. (TV: The Seeds of Doom)
