The DB4 GT Zagato is widely considered one of the most desirable Aston Martins ever made. Only 20 were originally built, making the GT Zagato DB4 a rarity among rarities. The design of the car was entrusted to the then-23-year-old Ercole Spada, who worked for the famous coachbuilder Gianni Zagato. This was the first of numerous successful partnerships between Aston and Zagato. Because these cars were hand-built, each has its own personality but all were lighter, faster, and slightly smaller than the Aston Martin DB4 they were based upon. The engines enjoyed a higher compression ratio than the standard DB4 and produced as much as 314 hp. The rolling chassis, complete with engines, were shipped to the Zagato factory in Milan where the lightweight alloy bodywork was created. In their day, the DB4 GT Zagatos raced well against Ferrari, Alfa Romeo, and others, and always looked and sounded fantastic while doing so.
