The Sixth Doctor and Melanie Bush once hired a green convertible Volkswagen Beetle from Bertie's Rent-A-Bug in Australia. Some time later, Mel was surprised to find that, instead of returning the car as he'd promised, the Doctor had decided to keep it aboard his TARDIS. Furthermore, he had replaced the car's collapsible roof with one the same colours as his trousers, and added a green sunstrip across the windscreen which read "The Doc" on the driver's side and "Companion of the Moment" on the passenger's side. Mel chided the Doctor for his dishonesty, and talked him into at least repaying Bertie's for the cost of the car. (PDA: Instruments of Darkness)

The Eighth Doctor kept a purple Volkswagen Beetle in an alcove in his TARDIS, which he and Sam Jones drove on numerous occasions. (EDA: Vampire Science, Longest Day, Seeing I) After the car was destroyed, the Doctor traded its remains to a Faction Paradox cultist in 2002 for information. Faction Paradox planned to take the car back in time and melt it down, ensuring its own steel would be used to build it and creating a "nice little paradox." (EDA: Unnatural History) The Doctor replaced the Bug with a Mini Metro which had a Volkswagen "VW" badge glued to its bonnet; one of his companions put a note on the car which read; "IT’S JUST NOT THE SAME, DOCTOR. GET RID OF IT." (EDA: Interference - Book Two)
