A fascinating combination of ingenious oleo-pneumatic, self-leveling suspension, elegant avant-garde styling by Robert Opron, and an exotic, quad-cam Maserati V-6, the Citroën SM remains among the most distinct and desirable GT cars of the past half century.

The SM offered here is one of 134 examples originally built for the US market that were instead sold new in Japan. Deemed by the NHTSA to be noncompliant with their 5 mph impact regulation due to the SM’s adjustable suspension and resultant non-fixed bumper height, these cars were ultimately earmarked for the Japanese market, complete with USDOT-mandated fixed headlights.

This Citroën eventually made its way to the US and was acquired by the consignor, a fastidious collector of pristine, unique postwar automobiles. In his care, the SM recently received more than $23,000 in documented mechanical work at The Creative Workshop in Dania Beach, Florida, in 2022. Offered with records dating back to the early 2000s, including invoices from noted model experts such as SM World, Bader Motors, and Citroën Concours of America, the car is further accompanied by its factory tool kit and various spare parts. Finished in its uncommon and stunning factory color of Gris Nacre (Mother of Pearl Gray) and featuring a Tobacco leather interior, this 1974 Citroën SM is a rare, provocative, and well-documented GT with otherworldly lines and innovative engineering.
