The winning bidder for the 1965 Aston Martin DB5 was not identified by RM Auctions officials.
It is one of only four cars originally constructed and used for 1964's Goldfinger and 1965's Thunderball as well as promotional tour use. The auction car was primarily used for promotion.
Some of the special James Bond options on the Aston Martin include Browning machine guns, a wheel-mounted tire slasher, a retractable rear bulletproof screen, an oil slick ejector and a smoke screen system.
Formerly the property of Sir Anthony Bamford, the famed James Bond Aston Martin was one of several celebrity cars offered from Tennessee's Smoky Mountain Car Museum, where it has been on display since the late 1970s.
