The DB4 is a sports car sold by Aston Martin from 1958 until 1963. It was an entirely different car from the DB Mark III it replaced, though the 3.7 L engine was externally visually related to the 2.9 L unit found in that car.
The DB4's unique design and performance would later form the basis for future Aston Martin classics, such as the DB4 GT Zagato, the Lagonda Rapide 4-door saloon, and its ultimate replacement the Aston Martin DB5.

Design
The lightweight superleggera (tube-frame) body was designed by Carrozzeria Touring in Milan, and its Continental looks caused a sensation on its unveiling at the 1958 London Motor Show. Although the design and construction techniques were Italian, the DB4 was the first Aston to be built at the company's Newport Pagnell works in Buckinghamshire, England.

Specifications
The 3.7 L (3670 cc/223 in³) engine, designed by Tadek Marek, was a dual overhead cam straight-6. It was prone to overheating at first, but the 240 hp (179 kW)[2] produced by the twin-SU carburettor version made buyers forgive this unfortunate trait. Servo assisted Disc brakes were fitted all around, with early 11.5 in (292 mm) Dunlops being replaced by Girlings. The independent front suspension used ball-jointed wishbones and coil springs and the live rear axle also using coils springs with location by a Watt linkage. Rack and pinion steering was used. There was a choice of final drive ratios, the normal one for British and European use was 3.54:1, the United States usually got a 3.77:1 and a 3.31:1 was also available for customers wanting a car with an especially high top speed.

Performance
A car with the British standard 3.54 final drive ratio tested by The Motor magazine in 1960 had a top speed of 139.3 mph (224.2 km/h) and could accelerate from 0-60 mph (97 km/h) in 9.3 seconds. A fuel consumption of 17.7 miles per imperial gallon (16.0 L/100 km; 14.7 mpg-US) was recorded. The test car cost £3967 including taxes.[2]

Production and models
1962 Aston Martin DB4 Series V Convertible There were five "series" of DB4s, with the most visible changes being the addition of window frames in Series II and the adoption of a barred (rather than egg crate) grille in Series IV. The Series V cars of September 1962 have a taller and longer body to provide more interior space, though the diameter of the wheels was reduced to keep the overall height the same. The front of the Series V was updated with a more aerodynamic look that was later carried over to the DB5 cars.

A convertible was introduced in 1962. It featured in-house styling similar to the Touring saloon, and an extremely rare factory hardtop was also available. In total, 70 DB4 convertibles were made from a total DB4 production run of 1110 cars[3].

This model is only made in 1961, one of only 165 and therefore very desirable. With it's round taillights, one of the nicest DB4. This car has the very rare Laylock De Normanville Overdrive and therefore reaches a topspeed of 240 km/u instead of the 223 km/h. Is still has it's original color, Snow Down Silver.

This example is one family owned car, the orginal owner passed away in 1981 and was mostly driven by his granddaughter who drove with him from the start on the backseat.The car was well kept in a special garage The condition of this car is mostly original, besides an engine overhaul in the 90's en a gearbox overhaul with new clutch in 2005, there's never been much worked on the car. Only maintained by original dealers and Aston specialists proved by maintenance records that are part from the impressive file that is well kept, with manual and everything.
