Auburn 851/852 Speedster

The Auburn 851/852 Speedster has retreated sharply in the Australian market, with the median price now sitting at AUD $137,500 and a year-on-year decline of 22.3 percent signaling sustained downward momentum.

The illiquid market conditions and absence of recorded sales activity in the past twelve months underscore how thinly traded these cars have become in the local market. With zero active listings currently tracked, buyers and sellers face significant friction in finding counterparties, which itself can amplify price volatility when transactions do occur.

Despite its "Holy Grail" collectibility score and status as an appreciating classic with only 600 units produced, the Auburn's current desirability rating has contracted to low, indicating waning appetite among collectors. Production scarcity and historical significance alone have not insulated the model from broader market headwinds affecting pre-war speedsters.

The outlook carries material downside risk. Base projections suggest a further 33.7 percent decline over three years to AUD $91,189, followed by a 41.5 percent cumulative drop over five years to AUD $80,392. These forecasts reflect the combination of low near-term demand and structural illiquidity that has plagued the segment.

Holders should treat the current SELL signal with seriousness given the confidence level is medium rather than high; without transaction data to anchor valuations, outcomes can vary. Timing any exit in such thin markets remains challenging, but waiting appears riskier than the execution costs of moving the car now.
