The thing that worries me about naming a machine Sexy is that the TARDIS has a habit of breaking down and not working properly if she thinks its in the Doctor's best interests.

On the other hand, we'd pretty much be guaranteed a car that likes us both, as you're the Doctor and I am your RoseDonnaAmyRomana.

Backup's a good backup (lol) name if we don't get a blue car. ;) Maybe I should tell my dad that. "It needs to be blue."
