For more than a century, the sports cars scene has been dominated by few notable brands that consistently make high-performance cars. Brands like Mercedes-Benz, Jaguar, BMW, etc., are among the top automakers that have distinguished themselves in the industry. While these cars generally don't come cheap, some of the models in those brand's lineups are so expensive, they can only be purchased by the insanely rich.

While these prices sometimes reflect the brand's status and quality of materials used in producing their cars, at other times, they reflect the level of technology incorporated in the vehicles. And when it comes to sports cars, there's no better reason to bump up their price tags than incredible performance.

Whatever the reason for their insanely exorbitant price tags may be, the following list will look at the most expensive sports cars on sale for every decade, beginning from the 1930s and ending in the 2010s. To give you an idea of what each of these sports cars would be priced brand-new, we'll also be adjusting their prices for inflation.
