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.

Buying Tips

  • Insist on a complete service history from a reputable SM specialist. These cars are notoriously complex and expensive to sort if neglected.
  • The Maserati V6 engine requires specific checks. Confirm the timing chain tensioners have been updated and that the original sodium-filled exhaust valves were replaced with stainless steel items.
  • Thoroughly inspect the hydropneumatic suspension. Check for fluid leaks, ensure the car rises correctly, and ask when the accumulator spheres were last replaced, as they are a regular maintenance item.
  • Look for rust in the floors, around the front subframe mounts, and under the front and rear window seals.
  • Test the DIRAVI steering to confirm it self-centers properly from a stop. Repairs to this system are complicated and costly.
