Goodwood – Building on the success of its market-leading £10.2 million sale at the Goodwood Festival of Speed, Bonhams|Cars is set to present an impressive sale at The Goodwood Revival Sale on Saturday 13 September. A notable early consignment is an Aston Martin DB4GT Zagato Sanction III, one of only two factory-approved examples crafted by renowned marque specialist R. S. Williams. This remarkable vehicle, a true masterpiece of automotive craftsmanship, will be offered with an estimate of £700,000 – 1,000,000.

The Aston Martin DB4GT Zagato is one of the most revered GT cars of the 1960s, originally conceived to take on Ferrari's dominance in international motorsport. With only 19 examples built between 1960 and 1963, these lightweight aluminium-bodied sports cars, styled by Carrozzeria Zagato, are now among the most sought-after collector cars in the world.

In the late 1980s, Aston Martin Works revived the legend with the Sanction II project, producing four cars utilising DB4 chassis with Carrozzeria Zagato supplying the coachwork. R. S. Williams, who supported that project, later secured permission to complete two further cars, again with Zagato bodies. These were designated Sanction III and delivered in 2000.

Bonhams|Cars now offers 'DB4/424/R', a one-owner car acquired directly from R. S. Williams upon completion. It has been meticulously maintained and regularly used, with over 44,000 miles covered. It is accompanied by comprehensive and meticulous documentation – from conception to the present day – in three bound volumes.

Tim Schofield, Head of Department, Bonhams|Cars U.K., said: "The Sanction III is an incredibly rare and fascinating chapter in the Aston Martin story; a car fully sanctioned by the factory and recognised as a Zagato with both AMOC and the Zagato Registry. '424/R' represents a near unique opportunity for collectors and enthusiasts alike."
