Mercedes-Benz W108/W109

The Mercedes-Benz W108/W109 has declined sharply over the past year, with median prices falling 25 percent to US$70,500 across a thin sample of five sales. The downward pressure contradicts its historical classification as an appreciating classic, and current momentum reads as distinctly negative.

Liquidity remains a significant constraint, with only five tracked transactions over the past 12 months and zero active listings in the current market. That sparse transaction volume limits pricing confidence and suggests sellers face a narrow buyer pool when bringing examples to market.

The W108/W109 sits in the collectible tier with moderate desirability, though production data and average mileage information are not available for this analysis. Without those benchmarks, it is difficult to assess whether this decline reflects cyclical weakness or fundamental shifts in collector interest for this model line.

The three-year and five-year projections paint a decidedly bearish picture, with base case estimates of US$36,920 and US$30,413 respectively—implying losses of 48 and 57 percent from current levels. These forecasts suggest the model faces prolonged headwinds, though the medium confidence level attached to these projections warrants caution before treating them as certainties.

The current signal leans toward waiting or selling rather than holding or acquiring at present prices. The combination of recent depreciation, thin liquidity, and negative forward guidance places prospective buyers and current owners in a period of reduced attractiveness for this model class.
