Funny. I actually have a guy in the neighborhood that has an Isuzu truc/suv and he painted it lime green with black acents, added big tires/wheels and paint the TONKA logo on both sides in big letters. It actually looks really cool.
had a friend that made signs too, my '01 had "Experimental Brakeless Vehicle" at the top of the back window. Also had "Caution this vehicle uses turn signals" but that one wore off thanks to the rear wiper
