Aston Martin DB2/4

In 1953 Aston Martin modified the DB2 by changing the rear of the body to a "fastbach" style with an opening rear hatchback door and window, the first ever on a high-performance car. The model was renamed the DB2/4 to denote the fact that a (minimal) rear seat was now included.

Within a year, a larger 2.9-liter engine was made standard for the DB2/4.

Aston Martin DB2/4 Mark II

The DB2/4 Mk II was mechanically the same as the DB2/4 but the rear fenders were squared-off and a "notchback" or hardtop body was offered. Only 30 of this new bodystyle were built.

David Brown acquired Tickford limited in 1954 and the bodywork for the MK II was the first to be made there.

Coachbuilder Touring of Milan built Spider convertible bodies on three of the chassis.

Engine performance was improved with larger valves and a redesigned camshaft.

Aston Martin DB2/4 Mark III

The DB Mark III was the final incarnation of the DB2. The DB Mk III featured a restyled front and Girling disc brakes on the front. Buyers could also choose an optional automatic transmission.

As in the DB2/4, The Mk III was built in a both a 4-seater Coupe and a convertible with bodies built by Tickford
