Duesenberg Model SJ

The Duesenberg Model SJ remains one of the rarest and most coveted automobiles ever produced, with just 36 units built during the marque's final years. Its status as a Holy Grail collectible is unassailable within the market, though the extreme scarcity and illiquid nature of these cars means traditional pricing signals are difficult to establish.

No sales of Model SJ examples have been tracked over the past twelve months, and there are currently no active listings in the market. This absence of transaction data reflects both the cars' rarity and the reality that ownership changes hands infrequently and often outside public channels.

The Model SJ's desirability among collectors remains rooted in its engineering legacy—supercharged power, hand-built coachwork, and its place as the final expression of American pre-war luxury engineering. Production numbers and the marque's historical significance ensure that any example commands serious collector attention whenever it surfaces.

Without recent sales or active inventory to reference, establishing current market valuation or directional momentum is not possible from available data. Prospective buyers or sellers of a Model SJ should anticipate that pricing will be negotiated on a case-by-case basis, informed by provenance, condition, and the particular coachwork rather than comparables.
