Great read!
My Fave paragraph:
Chevrolet decided to widen the tread and open the rear wheel opening which did not help the car in my opinion. They felt that they had to do something, so an SS model was also made. This idea was initiated by the observance of a black wagon with large special wheels that was spotted by one of the designers on his way to work one morning. It was owned by a dentist, he was persuaded to bring it in for display and, since larger wheels and tires would help any car, it received a lot of attention that resulted in the SS model.
HA!
