Auburn 851/852 Speedster

The Auburn 851/852 Speedster is trading at a median of £67,724 in the UK market, down 22.3 percent year-on-year, with a sell signal indicating ongoing weakness despite its holy grail collectibility rating.

This model remains exceptionally rare, with only 600 units produced across both generations, yet current desirability is rated low and the car sits in the illiquid tier—a divergence that suggests scarcity alone cannot drive demand in the present environment. No sales have been tracked in the past 12 months, which limits confidence in recent pricing signals but underscores how few transactions occur at any price level.

The three-year base projection falls to £44,914, representing a 33.7 percent decline from current levels, with the five-year outlook declining further to £39,596 or 41.5 percent below today's median. This extended weakness reflects both soft near-term demand and structural headwinds facing pre-war American sports cars in the collectible market.

No active listings are currently registered, which removes immediate supply pressure but also suggests owners are not rushing to sell into a weakening market. The combination of zero recent transactions, a sell rating, and depreciating status points to a market in transition rather than stable equilibrium.

Holders should prepare for material depreciation over the next three to five years unless broader demand for Auburn marque vehicles shifts unexpectedly. For potential buyers, the absence of liquidity and downward price trajectory may warrant patience for more attractive entry points.
