Over two-liter Grand Touring cars have always had a place to compete within the ever-changing regulations of international motorsports; the World Sports Car Championship from 1953-1961, the Speedworld Challenge from 1962-1963, and the International Championship of Makes from 1972-1981. This included racing in the great endurance races such as the 24 Hours of Le Mans, the 1000 Kilometers of Nürburgring, Spa and Monza, and the Targa Florio. Aston Martin, Ferrari, Jaguar, Porsche and Ford (by backing Carroll Shelby with the Cobra), all designed very lightweight, successful competition cars to compete in the GT category. In the USA these cars raced in the SCCA and the USRRC.
Today, GT cars qualify to race in many great historic events such as the Tour (de France) Auto, Tour of Spain and Targa Florio because they are dual-purpose race and street cars. They also qualify for the Le Mans 24 Hour Classic and, in the USA, the Monterey Historics and all other race events and tours. Due to their technology, great designs, event eligibility and low production numbers, GT cars have steadily been increasing in value.
