Part of what made Enzo Ferrari's sports cars so successful — outside of their race-bred pedigree — was Ferrari's willingness to cater to nearly every whim of his clients. Ferrari built a handful of cars with custom coachwork for European royalty, and this 1957 250 GT was delivered to Princess Lilian de Réthy of Belgium with one-off Pinin Farina bodywork. The design was a combination of current Ferrari styling with elements of its racing cars in the covered headlamps, along with a glimpse into the future with cues that would be seen on the upcoming Coupe. Princess Lilian received the car in 1958, and ten years later, she gifted the car to an Alabama-based Dr. Ernest De Bakey after he visited a hospital the Princess sponsored. The car is being offered at auction for the first time in 20 years as a spectacular example of the best in Ferrari's ultra-exclusive custom offerings.
