In 1928, Professor Narayan, the head of the Mythology and Folklore department at the University of Calcutta, owned a 1908 Rolls-Royce Silver Ghost, which the Fifth Doctor considered "a work of art." (AUDIO: The Emerald Tiger)

Spitfires and Lancaster Bombers, aircraft flown by the Royal Air Force in the Second World War, were powered by Rolls Royce engines. (TV: Victory of the Daleks, The Doctor, the Widow and the Wardrobe)

Circa 1973, the Third Doctor discovered that a matter transmitter was surreptitiously installed in the rear door panels of Sir Henry Felton's Rolls-Royce, by which Sir Henry was kidnapped by the aliens from Proxima Centauri to convince him not to divulge nor develop the matter transmission method he had discovered.

Also in the 1970s, the Master disguised his TARDIS as a black Rolls-Royce. (PROSE: The Face of the Enemy). A Rolls-Royce showed up out of nowhere in the middle of the English countryside; the mysterious man inside had a hypnotic effect on musical threesome, The Swifts. (PROSE: Smash Hit)

Among the recycled replacement parts on the the Doctor's TARDIS' console was a brass data plate from a Rolls Royce product. It read "Type FD 12 MK V11 Rolls Royce Motors Crewe England" and had a space in which to enter a NATO stock number. The Eleventh Doctor used the plate as a field expedient mirror with which to tidy his hair. (TV: The Angels Take Manhattan)
