Mini Metro

A Mini Metro was a type of car from 20th century Earth.

After the Eighth Doctor's Volkswagen Beetle was destroyed, he replaced it with an S-Reg Mini Metro which had a Volkswagen "VW" badge glued to its bonnet. He parked it in a corner of his TARDIS console room, where one of his companions had left a note on its windscreen reading "IT’S JUST NOT THE SAME, DOCTOR. GET RID OF IT." Sarah Jane Smith, who had managed to get into the Doctor's TARDIS while he was imprisoned, used the Mini Metro to drive around in the TARDIS' corridors. (EDA: Interference - Book Two)

Behind the scenes

 * In terms of UK-registered motor vehicles, the term "S-Reg" refers to a letter S on the vehicle's registration plate, in the space which would indicate when the vehicle was first registered and allow people to figure out the approximate age of the car. An S-reg would date the Doctor's Mini Metro as having been registered sometime between 1 August 1998 and 28 February 1999.
