Mercedes-Benz W108/W109

The Mercedes-Benz W108/W109 has fallen sharply in the UK market, with the median price dropping to £26,066 from roughly £34,750 a year ago—a 25% decline that signals meaningful headwind rather than seasonal correction. The SELL signal reflects this downward trajectory, though the medium confidence rating stems from a thin transaction sample of just two sales tracked over the past year.

Liquidity remains a constraint for this model, with zero active listings currently available and only two recorded transactions in the tracked period. This scarcity of sales data makes pricing validation difficult and suggests buyers and sellers are operating at considerable distance from each other on valuation.

The W108/W109 occupies the collectible tier with a score of 6, classified as an appreciating classic despite its recent depreciation. Moderate desirability underpins the segment—these are respected post-war Mercedes with engineering merit, but they lack the cachet or rarity that typically anchors price floors in downturns.

Base projections indicate sustained decline over the medium term, with the model expected to trade near £13,650 in three years (a further 47.6% drop) and around £11,245 by year five (56.9% total from current levels). These forecasts assume no catalytic shift in collector appetite or supply dynamics, and they warrant close monitoring against actual transaction patterns once more sales emerge.

Sellers holding W108/W109s should treat the current market with caution, as illiquidity combined with downward momentum creates risk of forced concessions. Any recovery would likely require a tightening of supply or renewed collector focus on post-war Mercedes chassis—neither of which shows clear signals at present.
