TARDIS (The Name of the Doctor)
From Tardis Wiki, the free Doctor Who reference
The First Doctor and his granddaughter nearly stole a faulty TARDIS from a repair shop when leaving Gallifrey.
As the Doctor had told his first TARDIS, (AUDIO: Prisoners of Fate) he had been leaving in a hurry, and he had to steal the first TARDIS he could "lay his hands on," so he couldn't take his old Type 50.
However, an echo of Clara Oswald appeared and told him he was making "a very big mistake" by stealing the wrong TARDIS. She convinced him to steal a TARDIS with a "knackered" navigation system that would be "much more fun". (TV: The Name of the Doctor)
Susan had already entered the TARDIS but after a quick discussion with Clara's echo, the Doctor pulled her back out and ushered into another one. (AUDIO: The Beginning)
