The Ferrari F50 GT is a rare beast indeed; only three were eventually produced.
The F50 GTs were designed to continue the racing success of the Ferrari 333 SP and F40 LM in the late 1980s and early 1990s.
Ferrari planned to race the F50 GT in the GT1 Class, where highly modified production cars from Porsche, Mercedes, and McLaren competed.
However, the FIA changed the regulations, and Porsche, Mercedes, and McLaren could very quickly build more competitive machinery.
In fact, Porsche publicly announced for the first time their 911 GT1, a prototype clothed in a sports car body.
The FIA allowed Porsche to build a small number of cars and, thereby, qualify as a homologated.
Ferrari petitioned the FIA to no avail. The FIA was pro-Porsche, meaning Ferrari realised they could not compete, so they ‘threw their towel in.’
Eventually, Ferrari only built three F50 GTs. They constructed six chassis but demolished the three unused chassis, preventing competitors from benefiting.
Ferrari offered the three completed motor cars to their ‘best’ clients with the strict proviso that they would never race them.
