The fat guy riding in the "Spohn" is Jimmy Dimora, an Ohio politician who is in the midst of a federal federal investigation of corruption charges related to taking bribes.
So, I suppose this one resides somewhere in Ohio. I can't find anything else about the car. However, the dashboard seems to be that of a 1950's Corvette. Did Spohn built any Chevy-based cars? If so, I'd guess this one was later modified to resemble the Batmobile.
