My proudest moments are beating Ferrari for the World Championship in 1965, and working with Ford to win Le Mans in 1966 and 1967.

No world championship has been easy for me.

A world championship medal on the road is something that I'm missing from my CV.

I got to experience a world championship with some great teammates.

They were ridiculous times. After I won my world championship in 1976, I went to Japan.

I've won a world championship, I know how that feels. I don't know how it feels to win a gold medal. I want to feel that; I want to know that.
