Well Benz Boy, I have reason to believe that the Company only ever produced two examples. One of course for Herr Nallinger, the other.....who knows. I do believe that the Nallinger car is in the museum. It certainly is a strikingly beautiful car.
Incidentally, just driving along the other day, I did see a 600 moving along at a good clip on the Cumberland Highway. There is no doubting its presence. Stunning. Regards Styria
