Combining Citröen's advanced chassis technology and Maserati's engine know-how, the SM (Série Maserati) featured DS-style hydro-pneumatic suspension, power-assisted, all-around load-sensitive disc brakes and fully-powered, self-centering steering that allowed the car to be set up with zero caster, thereby keeping the tires in full contact with the road at all times. Citröen had acquired Maserati in 1968, principally to acquire the latter's engine technology for its new top-of-the-range Gran Turismo Coupe, and the Italian firm responded to the brief with remarkable speed by the simple expedient of chopping two cylinders off its Indy four-cam 90-degree V-8 to create the required V-6. The styling of the SM was straight out of a 1970s' science fiction movie. The long sleek fastback body, with loads of glass and unadorned flanks, looked like some alien spaceship as it glided along on its self-levelling suspension with skirts over the rear wheels, hydraulically adjustable and swiveling headlamps under curved heated glass, and an asymmetric air intake on the bonnet. 

Citröen was the world leader in passenger car aerodynamics at the time, and the SM's class-leading drag coefficient enabled it to reach 140 mph, making it the fastest front-wheel-drive car ever at that time. Fondly remembered, these technically advanced and functionally beautiful cars remain highly sought after today. 


This fine example of the top-of-the-line SM model is believed to have been sold new in Switzerland, where it was purchased by collector Mr. Claude Imhoof in 1989. The car remained in Mr. Imhoof's ownership until 2017. Today, this SM shows less than 74,300 kilometers on the odometer - a figure believed to be original - and remains in highly original and carefully preserved condition throughout. Some paintwork might have been performed in the original color, but many factory decals and markings are still present as expected on such an original car. Shot on classic Michelin tires, one can just visualize Jane Fonda as a space-age Barbarella in the cult Roger Vadim film, grabbing the single spoke steering wheel of this SM to commute to her flying saucer.

I am not a natural flatterer, I like to think that I "tell it like it is", politely I hope. So when I tell you that I am very impressed by the contents of your website, it is just not English politeness. I of course love the subject matter but you deal with it in an energetic and respectful manner. I am overwhelmed by the research that has gone into compiling the list of coachbuilders/bodybuilders for Europe and North America. I have never heard of the vast majority of them. Congratulations on an excellent website.
