Launched in 1970 it used the underpinnings from the DS, which meant it had self-levelling hydro-pneumatic suspension, power brakes and good steering. Maserati produced a 170bhp, quad-cam V6 engine. Coupled with a stylish fastback bodyshell it should have been a good car. But the engine was complicated and it was inclined to rust. When Peugeot took over Citroen they sold off Maserati and ceased production of the SM. A good car now is sought after and owners cannot praise them highly enough. This book is full of contemporary road & comparison tests, technical & specification data, new model intros, driver's impressions & buyer's guide.
