A Bentley Mark II Continental was featured in the novel "Thunderball" and is Bond's final Bentley. Bond, having purchased the car in a wrecked state, upgrades the engine from a 4.5 L engine to a 4.9 L and has a custom drophead body from Mulliners. The Mark II was also grey; however, the interior was black leather. The Mark II Continental is last seen in the novel "On Her Majesty's Secret Service" where Bond upgrades the vehicles once again with an Arnott supercharger controlled by a magnetic clutch, causing Rolls-Royce, worried about potential damage to the engine, to disown the car. He uses the car in a race with the Contessa Teresa di Vicenzo in her Lancia Flaminia Spyder towards the beginning of the book. Bond dubs the car "the locomotive".
