Recognisably the same as earlier types, but distinctive, this was the last of the compact Aston Martins, for the DB4 which took over was much larger and heavier.
This time the standard 2.9-litre engine produced a credible 162bhp, though no less than 178bhp was optional.
Backing up this considerable power train were a hydraulically-operated clutch, and Laycock overdrive that was available as an option.
Borg-Warner automatic transmission could also be specified but only with the 162bhp engine.
With its body built by now David- Brown subsidiary, Tickford, rather than at Mulliners the DB iii had a modified front-end style, complete with a more curvaceous grille aperture, and less angular panel work to suit.
As before, the hatchback feature of the coupe was continued, although three different body types were still available.
According to a famous statement made by no less than David Brown himself, by the end of the Fifties, Aston Martin had succeeded in losing money on every car that they sold.
The last DB Mk III rolled off the production line at the Aston Martin factory in Feltham, which was soon to be closed.
This event doubly marked the end of an era, as the model had no obvious replacement.
