I don't design cars. I'm not a designer. I know what I desire to be built, I know what the end result is, the horsepower, the competition we'll be working against - but I leave it to the people who work with me to put it all together. I don't do anything.
The reason I moved to California the first time was to build the Cobra. I thought it was stupid to have a 1918 taxicab engine in what Europeans like to call a performance car when a little American V-8 could do the job better.
In 1964, when Lee Iacocca said, 'Shelby, I want you to make a sports car out of the Mustang,' the first thing I said was, 'Lee, you can't make a race horse out of a mule. I don't want to do it.' He said, 'I didn't ask you to make it; you work for me.'
I never had ambitions to see how rich I could get. I got a lot of contemporaries that that's their ambition, and I don't know very many of them that are happy.
