Help me name my new car, please!

I'm trying to come up with something fun for the license plate of the new car. Brian has decided he'd rather keep the older black elantra, and wants to keep the XVART plate on it. So now I need to come up with something for this one...

The DMV's site where you can check if the plate is available is here.

I'm leaning towards something TARDIS related because the car really does seem bigger on the inside than the outside! But the MY BMBLB plates just don't work. I'm turning them into the DMV for a refund this afternoon.
