Nice article. To me, the headlights and radiator look a little silly. But (lifting your picture, if you don't mind) this hunk of resin intrigues me:
It would be great fun to hack off the top, sculpt in a folded convertible top and, voila, desert staff car!
I agree with you that the car seems a little too high to be in-scale with 28mm minis, although, of course, figure bases would counteract this effect. I wonder if it would be possible to reduce the gap between the tires and the chasis, thus lowering the car a trifle?
