If race cars didn't race they wouldn't be race cars.
Their are several cars that don't qualify for a race because they where to slow. Only 43 race cars can be allowed to race so its not over crowded on the race track.
There are many places where a person can find images of race cars. One good place to find images of race cars are in books about racing. A local library or bookstore would have books with pictures of race cars in them. Also, many sites online have pictures of cars and race cars.
