Bonhams Greenwich 2026 Auction Results: Top Sales from the Annual Concours Event
The Bonhams Greenwich 2026 auction wrapped up on May 31 at the W.R. Berkley Corporation headquarters in Greenwich, Connecticut – the only Northeast sale on Bonhams|Cars‘ 2026 calendar. Running alongside the Greenwich Concours d’Élégance, the sale offered 52 lots and posted an 85% sell-through rate. No car exceeded its top pre-sale estimate, but two rare 1957 Porsche 356s dominated the results.
What Sold at Bonhams Greenwich 2026
Fifteen lots sold within pre-sale estimate ranges, and several no-reserve consignments changed hands below expectations. The biggest story of the day was a pair of 1957 Porsche 356As that accounted for the top two results of the entire sale.
The highest price of the day went to a 1957 Porsche 356A 1500 Carrera GT, which hammered at $511,000 against a pre-sale estimate of $500,000-$700,000.
What made this result stand out was the car’s condition – it was offered as something of an incomplete restoration, with a temporary engine powering it and the permanent engine not even being numbers-matching. Bonhams handled the consignment expertly, and the car’s documented history of period Cuban racing competition in 1958 drove strong bidder interest. Achieving $511,000 for an unfinished Carrera GT is a win for Bonhams and a compelling data point for the broader Porsche 356 auction market.
The second top result was the 1957 Porsche 356A T1 Speedster by Reutter, which sold for $291,000 – within its $250,000-$300,000 estimate.
Recent comparable sales put this result in context:
- RM Sotheby’s Monterey 2025 – 1957 Porsche 356A 1600 Speedster sold for $423,000 (fully restored, award-winning)
- Bring a Trailer, April 2026 – 1957 Porsche 356A Speedster hammered at $491,000 (no reserve)
The $291,000 Greenwich result likely reflects the car’s condition and T1 specification rather than any softness in the market. For a buyer willing to invest in a proper restoration, this could prove to be strong value – fully restored T1 Speedsters are consistently trading at $400,000-$500,000 and above.
Notable Non-Sale: 1991 Lamborghini Diablo
The 1991 Lamborghini Diablo – one of the most promoted lots ahead of the sale – failed to sell, with bidding falling short of its $300,000-$350,000 reserve. It was one of the more high-profile passes of the day and a reminder that even headline-worthy consignments are not immune to buyer selectivity in today’s market.
Bonhams Greenwich 2026: Key Takeaways
The Bonhams Greenwich 2026 sale reflected a measured collector car market heading into mid-year. Demand is present, but buyers are disciplined – no car exceeded its high estimate, and the liberal use of no-reserve consignments exposed some sellers to below-expectation results.
For Porsche 356 collectors specifically, the two results from Greenwich provide useful benchmarks ahead of the major Monterey Car Week 2026 auctions in August. The Carrera GT’s $511,000 sale – even in its imperfect condition – reaffirms the model’s enduring desirability at the top of the 356 market.
