The 250 GTO gradually passed into obsolescence following the 1964 season. Scuderia Ferrari withdrew the 250 GTO from its racing activity by 1965, leaving only a few independent teams and private owners to campaign it in endurance races, rallies and hillclimbs. By 1967, the 250 GTO was almost entirely absent from international racing, with only a few rally and hillclimb results during that year. Prior to the development of the 250 GTO collector market and associated vintage racing and show events, some of the surviving 250 GTOs were used in regional races, while others were used as road cars.
