Steve talked about the C111. I remember this car in Benz commercials in the late seventies to early eighties time period.
It was awesome standing next to this car in the MB Museum. I wore my wife out telling her what I knew about the car.
Sitting in front of the C111 is a streamliner that holds the world record for top speed on a public road. I can't remember the speed, I think it was something like 300MPH and was set on the AutoBahn south of Frankfurt many years ago. When I lived in Germany 30 years ago, I remember that stretch of AutoBahn being as rough as a cornfield. I wish I had paid more attention to the exact AutoBahn stretch and the year. I guess I'll have to do some research.
But I agree with Steve, I'll bet that turbo glowed.
