RM Sotheby's has announced plans to auction off the 2013 Aston Martin DB9 Spyder Zagato Centennial at their collector car auction in Monterey, California.

Built to celebrate Aston Martin's 100th anniversary, the one-off model is based on the DB9 Volante and features retro-inspired styling that will likely provoke love-or-hate-it reactions.  While the exterior styling is completely unique, the cabin largely carries over and features tan leather and green accents.

A 6.0-liter V12 engine resides under the hood and produces 510 bhp (380 kW). It is connected to a six-speed automatic transmission which sends power to the rear wheels.

The car currently has 2,300 miles (3,701 km) on the odometer and still carries a factory warranty on all of its mechanical components until March of 2016.

The convertible may not appeal to everyone but it's expected to sell for between $380,000 - $450,000 (€333,856 - €395,355).
