This is the TARDIS
It's from the long-running British sci-fi series Doctor Who, of which I was a huge fan when I was nine. I'm sure I still would be, if I watched television.
The TARDIS (an acronym for "Time and Relative Dimension in Space") is the malfunctioning time machine used by the show's eponymous character.
What's most impressive about the TARDIS is that it's ridiculously small on the outside, and huge on the inside.
Thus, considering my new car has similar proportions, "The TARDIS" is the new name for my car.
