Mercedes-Benz W108/W109

The Mercedes-Benz W108/W109 has declined sharply, with the median price falling to $70,500—down 25 percent over the past twelve months. The current sell signal reflects deteriorating momentum in what was once classified as an appreciating classic.

Liquidity remains thin, with only five tracked sales over the period, making it difficult for either buyers or sellers to gauge reliable demand or execute transactions without extended holding periods. This sparse transaction volume limits confidence in establishing floor prices.

The W108/W109 commands moderate desirability as a collectible sedan, scoring a 6 in collectibility terms. These are mechanically robust, long-running models with historical significance in Mercedes engineering, but they lack the aspirational cachet of contemporary high-performance variants or the rarity premium of lower-production siblings.

The three-year projection carries a sobering base case of $36,920, representing a further 47.6 percent decline from current levels. The five-year outlook settles at $30,413, a 56.9 percent drop. These estimates assume continued softening in the broader classic sedan segment without a catalyst for renewed collector interest.

Owners and prospective buyers should prepare for further price erosion unless market conditions shift materially. The combination of thin trading, moderate desirability, and negative momentum suggests this model remains out of favor in the current collector landscape.
