This 4 door hard top civilian Hummer is luxuriously complete with a winch, opening doors, adjustable rear view mirrors, white leather bucket seats, and a working tailgate. The front wheels are steerable, so this model could be motorized rather easily at the expense of interior decor. However, my motors were occupied elsewhere.
I have also used this model as a base for a military AM General HMMWV
