The Shelby GR-1 was a car I wanted to very much build. I could never get to the right person at Ford to get a license to build the car. The car is stunning in person, even better than the photos.
The doors on the Shelby GR-1 are known as butterfly doors. The Porsche 917, and McLaren M6GT had butterfly doors. In the 917 and M6GT, the pivots are just two rod ends.
