Not quite as clean as the O2 IMHO, but I think you have to wonder if this (minus the spoiler) is what a production model would have looked like. The concept had no rollbars, no cover, and probably only minor extra gusseting to compensate for the lack of a roof. Isuzu may very well have implemented this roll bar design to make it pass US safety standards and allow for some sort of top.

Bravo my Russian friend. Bravo.
