Aston Martin DB 2/4 Mark III
The Aston Martin DB 2/4 Mark III was a sportscar produced in 1957-1959. It was available in three body styles: 2-seat coupé, 2-seat drophead and 2+2 hatchback.
In Iam Fleming’s novel Goldfinger, the British Secret Service agent James Bond drives a DB Mark III, although Fleming calls it a DB III. In Fleming’s novels, this is the only Bond car to feature special gadgets. When the novel Goldfinger was turned into a movie, Bond drove an Aston Martin DB5 instead, which helped that car become one of the world’s most legendary sportscars.
In total, 551 DB Mark III cars were produced, most of them 2+2 hatchbacks. The 2-seat drophead coupé was made in 84 units, while the number of 2-seat fixed head coupés was no more than five. All the fixed head cars were made close to the end of the production period for the DB 2/4 Mark III and were given te mid-spec DBD engine. Unlike the hatchback, all the 2-seaters had conventional hinged boot lids.
