I agree that you need both. But a great driver can win in a good car more so than a good driver in a great car. I have seen guys step into cars they are unfamiliar with and win. A lot more racers are lost by the driver than the car.

I think Eric example is a good case study of that. The man has two cars and wins in both. One he just bought, I guess the question on the roadster is what was it's previous record with the last owner/driver?
