This open-top Ferrari 275 GTS convertible is both rare — only 200 were built — and has a royal provenance that makes it even more desirable. The 275 GTS was powered by the famous 3.3 Columbo V12 and shared its chassis with the fixed-roof sibling. The bodywork was penned by Pininfarina and differed substantially from the coupe, with open headlamps and a more luxurious interior. Bought by Prince Abdallah Moulay, the brother of King Hassan II of Morocco, the car remained in the royal family until the late '60s, when it moved to Casablanca under the ownership of a French ex-pat. From there, the car would travel to America, West Germany, and back to America, with a handful of refreshers and a repaint to red along the way. Now back to its unusual and original color, this 275 GTS has been driven — showing nearly 60,000 miles — and is ready to continue its journey with a new owner.
