Bentley 4,5 Litre Supercharged by Amherst Villiers
In the Bond novels Casino Royale and Moonraker James drives one of the last of the 4,5 Litre Bentleys with Amherst Villiers Supercharger. It's a battleship-grey convertible coupé from 1930. It is perhaps the most iconic Bentley, also reffered to as the "Blower Bentley", with its distinctive supercharger projecting forward from the bottom of the grille.
This is the first but not the only Bentley owned by James Bond. A 1935 Bentley 3½ Litre Drophead Coupe Park Ward with car-phone can seen in the beginning of the movie From Russia With Love (1963). In the movie Never Say never Again (1983), Bond drives a 1937 Bentley 4¼ Litre Gurney Nutting 3-Position-Drophead Coupé. In the novel Thunderball he acquires a wreck of a Bentley Mark II Continental, restores it and customises it, and calles it "The Locomotive". Bond purchases a Bentley Mulsanne Turbo (British racing green with magnolia interior) in John Gardner's Role of Honour. In the movie Never Say Never Again (1983) James Bond (Sean Connery) drives a 1937 Bentley 4¼ Litre Gurney Nutting Drophead Coupé. And in the novel Carte Blanche, written by Jeffery Deaver, Bond owns a new model Bentley Continental GT.
