Models like this are exactly why model contests have a Specialty category. It’s fun, unique, and cool. Dino Martinez shoehorned a way overscale Hemi engine into a Hot Wheels 1/18 scale die-cast TV-series Batmobile. Underpinnings include a Muscle Machines chassis and the mashup rides on wheels from a Jada Toys Dub City die-cast model. It’s great for playing chicken with a Penguin!
