Not really much to glean from these images, but its always nice to see prototypes around since that means they are doing their due diligence with testing.
I know its just because it is a mule, but the white horizontal bar in the grille inspires me. You could do a lot of cool things by just painting that bar in different colors.
Good point, something you would be interested in? I could see even matching it to the body color being effective. They're supposed to be black/dark grey
