Duesenberg Model SJ

The Duesenberg Model SJ remains one of the most rarefied automobiles ever built, with only 36 units produced during its manufacturing run. This extreme scarcity places it at the apex of American automotive collectibility, a distinction reflected in its "Holy Grail" classification.

Trading activity in the Model SJ market is virtually nonexistent, with no tracked sales in the past 12 months and no active listings currently available. This illiquidity underscores both the rarity of the model and the reality that transactions, when they occur, typically involve direct negotiations between elite collectors rather than conventional sales channels.

The absence of transaction data—both current pricing and historical trends—makes standard market analysis impossible for this segment. When cars of this caliber change hands, they do so infrequently and often with terms kept confidential by the parties involved.

For prospective buyers or current owners, the Model SJ functions as a crown jewel held for the long term rather than as a liquid asset. Any serious inquiry would require direct engagement with specialist dealers and auction houses familiar with ultra-rare prewar American iron and the collectors who pursue it.
