Silver trim along the sides of the car mode which become the arms was inspired by KARR from Knight Rider in his second episode.
Sorry the photos are blurry but I didn't have a good camera at the time. For some reason he looks a bit bluer in the montage pic than the correct purple he appears more in the Throttlebot group pic.


I think he got sold along with the other Throttlebots. I wonder if he's still out there somewhere or been thrown away like garbage.
