During the 1962-1964 racing seasons, only a few other GT-class models were consistently competitive with the 250 GTO. These were the Jaguar E-type, Aston Martin DB4 GT Zagato, DP212, DP214, and DP215, and the AC Cobras. In addition to official Scuderia Ferrari entries, many 250 GTOs were also raced by independent racing teams and private drivers. During this time it was therefore common for 250 GTO drivers to compete against other 250 GTOs. The 250 GTO was one of the last front-engined cars to remain competitive at the top level of sports car racing.
