Parnelli was just incredible but, he quit so soon. Only four years in the sprints with three championships and a 2nd in points. Only three years full time in the champ cars. After 1964, he only ran two or three champ car races a year and an occasional midget race around thanksgiving at Ascot. Gave up openwheel completely after 1967. The Turbine was his last ride. I was broken hearted when he quit but, now I'm glad he did. He's still with us, in great shape, and a great guy.
