What should I be paying?
One of the reasons that sales of the SM quickly tailed off is that buyers soon realised that servicing was not a one-stop shop. The car had to visit both Citroen and Maserati service centres, and while the engine was actually pretty reliable, the car’s quirks caught out many. Tales abound of cars being put up for sale because no local mechanic could figure out what was up with the SM, only for someone to buy it cheap, turn up, tinker with it for ten minutes and drive it away. Put it this way, you’ll need more than a Haynes manual if you’re intent on running an SM. Sort the aftercare specialist out before you buy the car.
The fuel tank is a vast 90 litres, and you should get around 22mpg from the 2.7-litre, so you’re looking at a range in the region of 430 miles. Better range than most modern GTs can muster. Later cars were fuel injected and a couple of mpg more efficient.
Back in 2020, we saw project cars at less than £10k, runners at £15k, those in general good nick were in the low £20k range, while absolute minters with back stories can command over £40,000.
