At the start of the Chaparral era, Jim Hall had no direct or substantial links to General Motors or Chevrolet, before he finished building his Chaparral 2. But one day, while he was at Elkhart Lake (Road America) for a sports car race with his Chaparral 1, he came across a prototype that Musser and his boss, Frank Winchell had on display. The car was the Monza GT and its mid-engine design piqued Hall's interest. He struck up a conversation with the two men and a new era in automotive aerodynamics was born.
