Introduced in October 1953 as the successor to the DB2, the DB2/4 was Frank Feeley's evolution of David Brown's first true postwar Aston: two small rear seats, a wraparound one-piece windscreen and — the innovation the name commemorates — an opening rear tailgate over a proper luggage bay, an unusually practical layout for a 1950s sports GT.
Across three iterations — Mk I (1953–1955), Mk II (1955–1957) and the DB2/4 Mk III (usually shortened to 'DB Mark III', 1957–1959) — the car migrated from the 2.6-litre W.O. Bentley-designed Lagonda straight-six to the 2.9-litre VB6J and finally to Tadek Marek's DBA-series revision of that engine in the Mk III. Coachbuilding responsibility moved from Mulliners of Birmingham to Tickford in Newport Pagnell in 1955 after David Brown bought Tickford, and the Mk III introduced the shape of grille that has defined every road-going Aston Martin from the DB4 onwards. It is also the car James Bond drives in Ian Fleming's original 1959 Goldfinger novel — before the DB5 took the role on screen.
The DB2/4 is the bridge between David Brown's earliest postwar Astons and the Touring-bodied DB4 that reset the marque in 1958. The Mk III introduced the trademark grille shape, disc front brakes and Marek's revision of the Bentley six — a genuine transition car rather than a filler model — and remains meaningfully cheaper than the DB4/5/6 lineage it enabled.
