Yeah, I remember that little thing. Was never really reliable, then again which soviet car ever was?
Niva is now owned by GM. They recently released the Chevy Niva Trophy. Which is not a one off, but a production model.
It comes with limited slip diffs front and rear, stiffer shocks, BFG AT KO tires (granted 28"), removable winch in front, roof rack along with hi-lift already attached to it as well as Hella lights on roof. There are also factory skids. No sliders, and a SNORKLE, out of all things! Engine bay is waterproofed, diffs, transfer and tranny breathers are extended higher up....
Ain't that weird?
