Aston Martin DB2/4 Mk III
The Aston Martin DB2/4 Mk III, produced from 1957 to 1959, represented the pinnacle of Aston Martin's first generation of post-war sports cars and served as the crucial bridge between the early DB2 series and the epoch-defining DB4. In many ways, the Mk III was the car in which Aston Martin perfected the formula that would make the DB series the world's most desirable grand touring cars.
The engine was the proven 2.9-litre twin-cam inline six designed by W.O. Bentley, now producing 162 horsepower in standard form or up to 195 horsepower in optional DBB specification with triple Weber carburetors and higher compression. This engine was robust, responsive, and endowed with a magnificent exhaust note that set the template for all future Aston Martins.
The most significant technical advance was the adoption of Girling disc brakes on all four wheels, making the Mk III one of the first road cars in the world to feature this technology. The brakes transformed the car's high-speed capability, providing fade-free stopping power that inspired confidence during spirited driving.
The body was redesigned with input from touring car racing experience, featuring a new grille design that was more clearly an ancestor of the DB4's iconic shape. The bonnet featured a prominent scoop, and the overall proportions were elegant and purposeful. Both fixed-head coupe and drophead coupe versions were available, with the fixed-head being more popular.
Driving the Mk III revealed a car of considerable sophistication for its era. The twin-cam engine was smooth and willing, the gearbox precise if slightly heavy in operation, and the handling competent with good grip from the independent front suspension. The ride was firm but not harsh, appropriate for a car intended for long-distance touring.
The interior featured traditional Aston Martin craftsmanship with leather seats, a comprehensive instrument panel, and high-quality trim throughout. The 2+2 seating configuration provided occasional rear accommodation, and the hatchback rear provided useful luggage space for touring.
Only 551 DB2/4 Mk IIIs were produced, all essentially hand-built at Aston Martin's Feltham factory. Today, the car is highly prized by collectors as the most developed example of the early DB series, offering genuine usability alongside undeniable beauty and racing heritage. Its significance as the predecessor to the DB4 adds further to its appeal.
Check chassis for corrosion, particularly around the suspension mounts and floor pans. The twin-cam engine is expensive to rebuild but parts availability has improved through specialists like Ecurie Bertelli. Disc brake components should be inspected for wear and condition. The David Brown gearbox is robust but synchromesh can wear. Body panels are hand-formed aluminum and expensive to repair. Authenticity is paramount for value; matching numbers engines and original specification command significant premiums.
Produced at Aston Martin's Feltham factory from 1957 to 1959. Total production was 551 units across fixed-head and drophead coupe body styles. The Mk III was the last Aston Martin produced at Feltham before the move to Newport Pagnell. Engine specifications varied from 162hp standard to 195hp DBB specification.
