The Appeal

The brilliant thing about Citroën of old, is you gain the impression that they cared far more about advancing the development of the motor car than they ever cared about making money.
The SM has to be Citroën’s ultimate passion project. Some say they bought Maserati just to use their V6 engine and the end product was a car so bristling in innovation that it defies belief. 
The antithesis of conventional, the SM broke all the rules and showed the world what a car could be, bankrupting Citroën in the process.
We’re delighted to offer this very original 1972 example which the vendor informs us has been cherished by the same Italian family since new. Following a recent rejuvenation which included a respray and comprehensive mechanical service, we’re informed that this wonderful Citroën is ready to be enjoyed.

The History and Paperwork

  • We’re informed that this car has been owned by the same family all its life
  • Retains its original instructional material and Turin dealer sticker on the rear bumper
  • Various registration documents present
  • The vendor reports that the car was recently serviced although its prior service history is unknown

The Interior

  • Exceedingly original with a rich patina
  • Unashamedly unconventional controls
  • Very usable in its current state of preservation
The SM’s otherworldly nature is not confined to the outside. It’s almost as if the interior appointments are lifted straight from a ‘50s sci-fi spacecraft, which we find immensely endearing.
As you step aboard, the gold coloured dashboard fascia greets you with an array of oval Jaeger instruments, all of which look to be in very good condition. We particularly enjoy the prominent red warning light labelled ‘STOP’, commanding you to bring the vehicle to an immediate halt in the event of anything untoward. Despite a life in the Italian sunshine, the top of the dashboard looks to be free from UV damage which is great to see. 
The centre console is similarly charming and aesthetically pleasing. The vendor points out the highly desirable original radio which we understand to be in good working order, along with all the other switchgear besides the electric windows, which do not currently work.
We’re informed that the black leather upholstery is original and it has certainly accrued a rich patina with the passage of time. Apart from some creasing and light cracking, we couldn’t discern any damage beyond what we’d classify as wear commensurate with age. Overall, the upholstery presents really well and we’re glad that it has been preserved rather than replaced.
The carpeting is showing some signs of age and is quite discoloured in places. There’s every possibility that it is original to the car, and being 51 years old now, it’s survived incredibly well.
One of the strangest features of hydropneumatic Citroëns is the pedal layout and you’ll note that where you’d normally find a brake pedal, a peculiar rubber device known as the ‘mushroom’ sits flush to the footwell. There is little in the way of wear to the controls and nothing you wouldn’t expect to see with a car of this vintage.

The Exterior 

  • Elegant styling courtesy of Robert Opron
  • Recently repainted in white
  • Straight bodywork and sound underpinnings
Robert Opron’s teardrop styling not only made the SM beautiful, it also made it incredibly slippery with a drag coefficient of just 0.26Cd. It effortlessly combines crisp edges with voluptuous curves and is a real lesson in elegant design. With a narrower track at the rear, the back wheels tuck into the tapering body line and the car culminates at an abrupt Kamm tail.
This example has apparently been repainted recently and this looks to have been completed to a high standard. The bodywork appears really sound with no obvious signs of corrosion. A glance at the floor pans when the car is in its highest height setting suggests the monocoque to be in really sound order and vendor comments that it is free from rust.
All of the trim and glassware present well for their age, with no obvious signs of accident damage or deterioration. The wheels bear a few marks but remain very serviceable. 
Overall, this is a smart example that’s not been over-restored.

The Mechanics 

  • 2.7 litre Maserati V6
  • Five-speed manual gearbox
  • Variable power assisted steering
  • Self-levelling hydropneumatic suspension and braking system
  • Recent fluid service with all spheres replaced and belts changed
It would take all day to list the SM’s innovations but at the heart of most of them lies the hydropneumatic system, running off a peculiar green fluid called LHM. It’s responsible for the adjustable self levelling suspension, self-balancing brakes and Diravi self-centring steering.
All of the hydraulic spheres have apparently been changed  and the vendor informs us that the hydropneumatic system on this car is in full working order with no issues to report. 
As if the SM wasn’t special enough already, it is of course powered by a Maserati V6 which drives the front wheels via a five-speed manual gearbox. The vendor tells us that the engine was recently serviced with new belts, plug leads and exhaust tail pipes. 
We’re informed that the car drives immensely well, rides beautifully, changes gear smoothly and comes to a stop in a timely fashion.


There’s so much to love and admire about the Citroën SM. This is a delightfully original example and therefore a fabulous collector’s item that we’re sure will provide endless entertainment.

About Max Bids

The max bid process allows you to bid without any hassle.

Enter your maximum bid and we will then bid on your behalf to ensure you're the highest bidder - just enough to keep you in the lead and only up until your maximum.


Car & Classic prevent auction snipers from bidding in the last seconds to win an auction.

Auctions are extended by 3 minutes if anyone bids within the last 2 minutes to allow other bidders to react and counter-bid.

Auto-bidding increments

  • If your maximum bid is equal to or below the reserve price, your maximum bid will be applied in full if you are the highest bidder.
  • If you are the highest bidder and place a maximum bid above the reserve, we will automatically put in the reserve as your first bid.
    • Once the reserve has been met, Car & Classic will make sure you are the highest bidder using only the bidding increments stated below.
    • We will keep you in the lead up until your maximum bid OR the increment closest to your maximum bid, providing your maximum bid is enough to cover the increment value.

Bid Amount Increment
€0 to €9,999 €100.00
€10,000 to €49,999 €250.00
€50,000 to €99,999 €500.00
€100,000 + €1,000.00

Automatically outbid immediately

When you place a max bid and are outbid immediately that means that another bidder has placed a max bid limit which is higher than yours.

You can bid again and we will use our automatic bid system to try and get you as the highest bidder.

Matching max bids

When there are two max bids of the same value, the one placed first remains the lead bidder.


We may hold a pre-authorisation charge on your card until the end of the auction when the hold will be cancelled. If you win, we'll take a security deposit which counts towards the payment for the vehicle and isn't any extra cost to you.

What are pre-bids?

A pre-bid means you're able to place a bid before the official start of the auction.
You will be notified whether or not you are the highest bidder when the auction starts.

Problem with your bid

Bids are contractually binding. To help protect you, we have some rules in place if we think it's been mistyped. Please check and amend what you have entered.
