Citroën SM

The Citroën SM occupies a narrow and illiquid corner of the UK classic market, with a single tracked transaction in the past 12 months establishing a median value of £26,193. Without a second comparable sale, year-on-year trend analysis is impossible, and the absence of active listings suggests these cars rarely cycle through the market.

Production totalled just over 12,900 units across the model's lifespan, making the SM a genuinely rare French saloon. Its classification as appreciating classic and a collectibility score of 7 reflect the model's mechanical significance and design credentials, though current market desirability registers as low relative to other cars in its vintage tier.

The single-transaction sample size means any pricing conclusions carry minimal statistical weight. For buyers or sellers contemplating a move, this thinness of comparable evidence makes negotiation more art than science, and liquidity risk is material.

Without mileage data from recent sales, typical condition profiles on transacted examples remain unclear. This gap also underscores the scarcity of reliable transaction evidence in this segment.

No forward projections are currently available, reflecting both the absence of trend data and the structural illiquidity that makes forecasting fraught.
