Funny story about the Sunstar DMC...
I can tell you EXACTLY why the Mr. Fusion looks like that!
I was working at Universal Studios Hollywood, and my big thing was getting the screen used Delorean restored, mostly because of the Frankencar they turned it into.
BEFORE I had the work done and they used my Krupps and screen-used base to have an accurate replica made and installed, the guys at the Tram Garage who were in charge of maintainance made this...

...out of rolled sheet metal, a base from the BTTF The Ride vehicles and a wood plug at the top.
When the Mr. Lin from Sunstar came out to research the vehicle for their car, I grabbed my keys and gave him the grand tour, inside and out.
I ALSO gave him pics of the "real" Mr. Fusion and went into great detail about the screen accurate version...unfortunately a good portion of our conversation was lost to the language barrier between us...obviously
Their attention to detail is outstanding! The Mr. Fusion on their car looks JUST LIKE this one
