Duesenberg Model SJ

The Duesenberg Model SJ remains a foundational pillar of automotive collecting, with only 36 examples built and a perfect collectibility score reflecting its status as a Holy Grail machine. No transactions have been tracked in the UK market over the past year, making current pricing and recent directional momentum impossible to establish with precision.

Liquidity for the Model SJ is effectively non-existent in the tracked data, with zero active listings and no sales recorded in the monitoring period. This scarcity should not be mistaken for weakness; rather, these cars trade so infrequently and often outside public channels that market sentiment remains difficult to quantify.

The classification as an appreciating classic underscores collector conviction in the marque's historical significance and engineering legacy. Condition and provenance dominate valuation far more than mileage, given the rarity of any specimen and the decades separating most examples from their final regular use.

Base case projections suggest 15.5% appreciation over three years and 21.0% over five years, reflecting the structural scarcity and enduring demand among elite collectors. These figures should be read as directional indicators rather than price-point forecasts, given the absence of recent transaction evidence in the monitored market.
