Tried for a while now, that is how far I got. I tried to build it in the Roth colors, meaning white with brown scallops, but that would require decals. I decided to go with the Hot Wheels colors, and lime seemed doable (and white, and red, and blue, and grey). However, based on the Hot Wheels toys, I fiddeled around with the bubble, can't decide on color yet. Engine is just a place holder, no interior yet, and some other things left to do...
