Duesenberg Model SJ

The Duesenberg Model SJ occupies the rarest tier of automotive collectibles, with only 36 examples produced during its manufacturing run. This extreme scarcity places it at the pinnacle of classic car desirability from a historical standpoint, though Australian market data remains too sparse to establish reliable pricing or transaction patterns.

No sales have been tracked in the Australian market over the past year, and there are currently no active listings, reflecting the profound illiquidity that characterizes this marque in the local market. This absence of transaction data means any valuation would rest entirely on international auction results and private treaty comparables rather than domestic market signals.

The Model SJ represents engineering and design achievement from the pre-war era that remains unmatched, securing its "Holy Grail" status among serious collectors. When examples do surface globally, they command prices reflective of their mechanical sophistication, bespoke construction, and historical significance—though actual market movement in Australia cannot be quantified from current data.

Buyers seeking a Model SJ should expect to source one internationally, as domestic availability appears non-existent at present. The lack of Australian transaction history makes this one of the few ultra-rare classics where collectors operate almost entirely outside established market infrastructure.
