You're quite right about the big dollar engine issue, some people have money and will spend it. But just as it's always been (in all forms of motorsport), it's a kick to compete with older technology and less horsepower -- and be successful. No, you're not likely to win a national championship with a 160mph SC car, but it sure is fun to put the 185mph guy on the trailer, and with a little luck take home the trophy.
