The DB4 is a sports car sold by Aston Martin from 1958 until 1963. Technically it was a further development of the DB Mark III it replaced but with a completely new body.The DB4's design 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.
