Mercedes-Benz W108/W109

The W108/W109 Mercedes-Benz has retreated sharply over the past year, with the median price falling to £26,066—a 25 percent decline from twelve months prior. The SELL signal reflects sustained downward pressure, though the small sample size of just two tracked transactions warrants caution when extrapolating broader market direction.

Liquidity remains severely constrained, with no active listings currently on the market and only two sales recorded across the tracked period. This thinness makes execution difficult for sellers and creates unpredictable pricing gaps between individual transactions.

The W108/W109 occupies the collectible tier with a score of 6, driven by its status as a significant post-war saloon design, though moderate desirability and absent production-volume data suggest the market views these cars as secondary-tier classics rather than blue-chip holdings.

Base projections point to substantial further erosion. The three-year outlook calls for a decline to £13,650 (a 47.6 percent loss from current levels), with the five-year estimate settling near £11,245 (56.9 percent decline). These forecasts assume continued softness in the appreciating-classic segment without a meaningful shift in collector interest.

Mileage data is absent from the recent transaction record, making it difficult to assess whether condition variance or age-related wear is influencing recent sales prices. Prospective buyers should establish clear condition benchmarks independent of the thin market evidence available.

The confluence of negative momentum, illiquidity, and weak forward guidance suggests patience may be warranted for potential buyers, while current holders face a difficult choice between accepting near-term losses or betting on a reversal that the data does not yet support.
