Mercedes-Benz W108/W109

The Mercedes-Benz W108/W109 segment in Australia is signaling weakness, with the median transacted price at AUD $52,921 down 25 percent year-on-year. The single tracked sale in the past year reflects thin trading activity and makes trend interpretation difficult, though the directional move is clear.

Liquidity remains the primary constraint for this market. With no active listings and only one recorded transaction across a twelve-month window, buyers and sellers face a genuinely illiquid category where pricing discovery is minimal and holding periods will likely be extended.

The W108/W109 carries a collectible classification but scores modestly on desirability metrics, reflecting its position as a respected but not highly sought classic Mercedes platform. These cars appeal to period-correct enthusiasts rather than commanding broad collector interest, which caps both demand and price stability.

The outlook presents headwinds over the medium term. The base projection assumes a 47.6 percent decline to AUD $27,714 within three years, with further erosion to AUD $22,830—a 56.9 percent drop—by the five-year mark. Depreciating status and a sell signal suggest the market has already repriced these vehicles downward and may continue to do so absent renewed collector appetite.

Given the illiquid trading environment, the modest sample size, and the continued downward projection, owners should prepare for sustained pricing pressure. Any purchase decision should factor in both the scarcity of available stock and the historical difficulty in achieving timely exits.
