Over the years Italian coachbuilder Zagato has been responsible for some of the most beautiful cars around. Recently they have worked with BMW and also Aston Martin, but today we want to present you a very special car by Zagato and Aston Martin, that was built in 1962. Limited to only 19, Zagato was officially hired by Aston Martin in 1962 to build a limited run of re-bodied cars. Zagato did not only style the limited edition car, they also made it perform better, making it lighter and stronger. The result was that the Aston Martin DB4 GT by Zagato was one of the fastest cars of its time and a direct competitor of the Ferrari 250 GTO. RM Sotheby’s has one of these beauties up for auction on December 10 with estimates going as high as $16 million.
