You know what I think about this model already man, and nice renders
Yeah, what marvin said is pretty much the case. The car did a promo tour, and was sold a couple times between the original movie and the sequel, and stripped of those parts, so they had to be replaced, there was also a clone car made for running shots and the wreck scene, which wasn't quite accurate to either the original vehicle in mad max, or in road warrior either. They had to, or chose to, replace the huffer, zoomie sidepipes, rear wheels, and a few other details, besides the monster chop job on the rear end...
Seems pretty accurate to the sequel car to me, which is what he was modelling anyways
Great job
