The Energon Pub

I was wondering if anyone knows anything about the Bumblebee-colored Datsun that was seen on the DOTM set during filming. I would think that it was just a normal car, except for the fact that (IIRC) Shia and/or Rosie were seen near it and the fact that it's colored like Bumblebee don't seem like just a coincidence.

It's Sam's car now that Bumblebee has formally joined NEST and is with the other Autobots.
