It's cool enough to have a realistic Bumblebee costume, but what makes this one Neato is that it actually transforms from robot to car mode. I don't have any more information about this clip. CrunchGear thinks that it's being used as a promotional gimmick in a car dealership, which seems like a reasonable guess.

Uncomfortable-looking, but neat.
Also, God, I would love it if the real Bumblebee would transform that slowly, awkwardly, and self consciously.

Ridiculously good.
It's a stretch, I know.
