If you're a James Bond fan, you'll soon have the chance to own the biggest piece of the secret agent's memorabilia.  RX Auctions is auctioning off the Aston Martin DB5 that Sean Connery drove in the 1964 hit film "Goldfinger" during Automobiles of London event on October 27.  Auction organizers say it could bring at least $5 million, which would be the highest amount ever paid for a piece used in a movie.  Everything in the car is functional, including the retractable machine guns, rotating license plates, oil slick sprayer, bulletproof rear window shield, and smoke screen device.  One would hope that the guns have been disabled and can't be loaded.  There were originally two versions of this car, but the first one, which was auctioned twice, was stolen from a Florida airport in 1997 and was never recovered.
