Citroen SM

The Citroen SM was born from Citroen's 1968 acquisition of Maserati. It combined Citroen's advanced hydropneumatic suspension and chassis technology with a new, compact 2.7L Maserati V6 engine. The result was a futuristic grand tourer that looked and drove like nothing else, featuring innovations like self-centering DIRAVI steering and a slippery, Robert Opron-penned body.

Collectors prize the SM for its unique blend of Italian performance and French avant-garde design. It's a complex car that requires specialist knowledge, but rewards owners with an unparalleled driving experience. European-spec cars with their six swiveling headlights are particularly sought after, though all SMs represent a high-water mark for 1970s automotive engineering and style.

The SM market is well-established, with an average price around $37,000. While project cars can be found for under $10,000, top-tier restored examples can exceed $80,000. The car's maintenance demands tend to keep prices accessible to serious enthusiasts, ensuring that most buyers are committed to preserving these unique vehicles.

Based on 67 recent sales, prices range from $3,900 for projects to $83,000 for top examples.
