I've been a devoted race fan all my life and Toyota is the least of my concerns with NASCAR. I prefer American cars but when you attend a Cup race there are Toyota fans and they provide some nice displays for the fans. I don't get some of the hate for the Toyota drivers. I would drive one tonight if that was a way to get a Cup ride.
It will probably keep the US based teams on their toes. Just imagine what an American can would be "quality wise" if there was no Japanese competition. The current crop of US cars is MUCH better because they have to be.
