Is the Rolex 24 the race with the most superstars in the world?

I believe so but could you think of another race with so many star drivers? Also I love the unique and one time occurrences like Danica Patrick driving for Richard Childress and the stock car drivers getting in sports cars. You also can't forget the privateers.|||It might be, but it depends on what you consider a "superstar" is. I would go so far as to say that Le Mans has more superstars, but that is because I think Le Mans is a bigger race than the Rolex 24 and has more people involved in it.|||It's one of the biggets races.
