It was great to see the American Lemans Series cars.
The variety makes for a better overall race weekend. It was good to see the Champion Audi win instead of the Joest team for a change. It looked to me like the three classes competed as well on the narrow Miami street course as they do on the more open Sebring circuit. Charlotte is not much of a Porsche fan but I always like to see the parade of 911's compete in the GT class.
After the Miami weekend I'm convinced that the ALMS is a better show than Champ Cars. It's a purer form of motor sport. The ALMS has less flash, less commercialization, and less hyperbole, but also has extremely fast and high-tech cars. The drivers and owners seem to be more interested in the driving and competition for the sheer enjoyment of racing than the CART teams and drivers.
