More specifically, the car with all the expensive special effects gadgetry was a DB4 prototype made to look like a DB5.
What isn’t as well-known is that there were actually two DB5s used during filming. 303 machine guns, a bulletproof rear window, an ejector seat, battering ram bumpers, vicious tire slashers, and what may have been the first-ever in-car navigation system. Special effects gadgetmaster John Stears gave it revolving license plates, twin Browning. Bond’s car was outfitted with several features that the road-going model didn’t have. By the time the film version was in production, the DB5 was Aston Martin’s new hotness, and thus, James Bond’s, as well. In Ian Fleming’s original novel, 007 drove a DB Mk III.
Named for British industrialist David Brown, who purchased Aston Martin in 1947, the DB5 first graced British roads in 1963.
