Things went pretty great for Aston Martin->ke13 during this weekend: next to unveiling the CC100 Speedster, the company also obtained a record auction price for a unique DB4GT. The car was part of the Aston Martin Centenary Sale at Aston Martin Works on 18 May 2013, which totaled a record total of over £10 million (more than $15 million), with every lot sold.

The DB4GT was auctioned for an impressive amount of £3,249,500 (a little over $4.9 million) - the highest ever price paid for an Aston Martin at auction.

However, this is not a regular DB4GT: it is nicknamed "The Jet" and was the last DB4GT to be built. The model is a one-off edition and has been designed by the Italian design house Bertone. The model was unveiled at the 1961 Geneva Motor Show.

This unique DB4GT won a total of 12 awards, including first in class at Pebble Beach and the Hurlingham Club, and best in show at Villa d'Este.
