6. 1958 Ferrari 250 Testa Rossa
Identified by many as the most important Prancing Horse in Ferrari’s deep stable, the 250 Testa Rossa dominated the racetrack during its day and set the standard for the future successes of the Italian automaker. Built with both performance and reliability in mind, this sexy if unorthodox roadster was well-suited to endurance races, and even won the 24 Hours of Le Mans in 1958. This ideal combination of sport and sensibility has helped the Ferrari 250 TR to remain popular with collectors today, many of whom are willing to throw down big bucks for the little two-seater. In fact, one particular 250 TR set a new world record auction price for a car in August 2011, selling for an astounding $16.4 million.
