Ugliest...car...ever???
Doubt it, what about the Fiat Multipla, Renault Avantime, or the Nissan Micra. And those are actually production cars, look 'em up. I think you will find that they take the cake.
As for the Rosemeyer, I think it's beautiful. It is sculpted and bold and designed single-mindedly to do one thing. It is designed to go unbelievably fast, just as it's namesake did in the 30's. Study pre-WWII Auto Union's and Mercede's, you will find amazing motoring feats. They had technology far ahead of it's time.
Bernd Rosemeyer himself was a rocket. Sadly, he died in an Auto Union streamliner in 1938 while setting a speed record in Germany. He was driving at 270 MPH when a crosswind threw his car off the track. Look it up, it is a fascinating history and a bold car.
