In 2013, Aston Martin->ke13 unveiled a pair of stunning Zagato-built->ke3827 one-offs as part of its 100th anniversary celebration. Both ditched the design of the production cars they were based on in favor of a "more Mediterranean" appearance that made them unique among other Aston Martins. These special editions were the DBS Coupe Zagato and the DB9 Spyder Zagato. The DB9-based->ke210 convertible will be looking for a new owner at RM Sotheby’s car auction->ke2845 at the 2015 Pebble Beach Concours d’Elegance->ke2839 on August 14th.

Built for U.S. Aston Martin collector Peter Read, the DB9 Spyder Zagato Centennial is based on the DB9 Volante, but features reworked body panels with squared-off edges, wider rear fenders and a more aggressive rendition of the brand's trademark front grille. Unlike other Aston Martins, the Zagato's headlamps were incorporated into the mesh, while the taillights had a teardrop shape.

The auction house estimated the unique convertible will fetch between $380,000 and $450,000.

RM Sotheby's car sale at Pebble Beach will also see an array of classic sports cars->ke506 go under the hammer. Highlights will include a 1968 Maserati Ghibli 4.7 Spyder Prototype ($1,200,000 - $1,800,000), a 1970 Ferrari 365 GTB/4 Daytona Berlinetta ($900,000 - $1,200,000), and a 1976 Lamborghini Countach LP 400 ’Periscopio’ ($1,500,000 - $2,000,000).

Why it matters

It's a bit surprising that the owner of this unique piece of art decided to put it up for auction after less than two years of ownership, but it gives other collectors a shot at one of the rarest modern Aston Martins ever built. The estimated bid between $380,000 and $450,000 seems like a lot given it would be about double what Aston Martin charges for a new DB9 Volante, but it seems as a solid investment considering Zagato-bodied sports cars tend to gain a lot of value over time. It may not be the most valuable car to go under the hammer at Pebble Beach, but it's definitely the most appealing modern vehicle on sale.
