James Bond’s car in “From Russia with Love” is an unusual one for the series, as the Bentley was almost 30 years old at the time of the film’s release. This was 1935 Bentley 3.5 Litre Drophead Coupe Park Ward.
In several of the Ian Fleming novels, Bond had driven a Bentley 4.5 litre, which predated the Mark IV by two years by the way. This was likely the inspiration behind its inclusion in the film.
It seems it was about that car James Bond asked Q “Where’s my Bentley?”. But the 1935 Bentley 3.5 Litre Drophead Coupe Park Ward was only time 007 drives a Bentley in entire Eon Production series.
