Duesenberg Model SJ

The Duesenberg Model SJ remains one of the most exclusive automobiles ever built, with only 36 units produced during its production run, placing it firmly in the "Holy Grail" collectibility tier for classic car enthusiasts and institutional collectors.

Current market data for the Model SJ is exceptionally sparse, with no tracked transactions in the past twelve months and no active listings in the market. This scarcity of transaction data reflects both the extreme rarity of these vehicles and their tendency to remain in long-term private collections rather than circulating through conventional sales channels.

The illiquid nature of Model SJ sales means that pricing discovery occurs through sporadic private negotiations and occasional museum or estate dispersals rather than regular auction activity. Any collector considering acquisition should expect an extended search timeline and direct outreach to known holders, as these cars rarely advertise themselves openly.

Without recent comparable sales, establishing a current market median or directional pricing signal is not feasible at this time. Historical precedent suggests Model SJs trade in the multi-million-dollar range when they do appear, but updated market positioning cannot be determined from recent activity alone.

The desirability profile for Model SJs has historically been sustained by their engineering significance, pre-war pedigree, and extreme low production numbers rather than by steady collector demand. Owners of these vehicles tend to hold for decades, which constrains the supply available to new buyers at any given moment.
