There was a website which showed a factory R129 that was painted orange for testing. It showed the strength of the A-pillars of the R129 in a rollover situation with sequential photos. They also showed another photo shoot of the R129 as it was driven onto a corkscrew ramp which flipped the car on it's side and eventually onto it's roof. It was really impressive to see firsthand the tremendous strength and quality built into these German commuter tanks. I will try to find it in my viewing history or via Google.
