For some auto enthusiasts and thrill seekers, it isn't enough to own a fancy sports car. These speed demons compete on tracks around the globe in real-world races like the Daytona 500 and 24 Hours of Le Mans.

The cost of sitting behind the wheel is usually about $150,000, but some choose to pay for an entire three- to five-man crew, which can cost north of $400,000. Higher performance cars mean even higher price tags.
