About the Citroën SM

The Citroën SM, a high-performance grand tourer produced between 1970 and 1975, represents the radical intersection of French aerodynamic innovation and Italian mechanical muscle, with current market values in 2026 typically ranging from $35,000 for usable drivers to over $145,000 AUD for pristine, fuel-injected European-spec models. Its desirability is driven by its status as a "technological masterpiece," featuring a Maserati-sourced V6 engine, self-levelling hydropneumatic suspension, and the revolutionary DIRAVI self-centring steering, all encased in a Robert Opron-designed body that remains one of the most aerodynamic silhouettes ever produced. The buyer pool is a highly specialized group of connoisseur collectors and engineering purists who are willing to trade the complexity of its specialized maintenance for its "Concorde of the road" driving experience, while in Australia, the scarcity of the model—with only a small number of private imports and no official right-hand-drive production—has made well-maintained survivors blue-chip assets that command a significant premium over the more common DS.
