No pic for me, either.
The Iltis was, quite simply, the wrong vehicle. The Germans designed the Iltis as a Liason Officers vehicle. That's it. At the exact same time the Iltis was in use with the German Bundeswehr, so was the Gelandewagen. The Iltis was designed to be small, light, and cheap, with limited usefullness.
It was never designed for patrolling, putting weapon stations on, command, recconnaissance, or any other such task. It was never (quite obviously!) designed to take the roof off and operate in the rain.
The fact that it could do much more than it was designed for speaks well for it.
But we bought the wrong vehicle, for the wrong reasons, at triple the price.
