The GTAm models are derived from Alfa's 1750 Veloce coupe. The Am suffix is a shortened version of "America," and refers to the US model, which required fuel injection for emission reasons. With full development, the GTAm engine brought twice the brake horsepower available from a standard carbureted car. The bodywork featured fiberglass doors, hood and dashboard and riveted fiberglass fenders. It featured the typical Autodelta sliding-block rear suspension to lower the car's roll center, thereby improving handling. The cars ran on 13-inch Campagnolo wheels and had ventilated disc brakes. A new dual-plug cylinder head was used, and the engines were available with either 1779-cc or 1985-cc displacements.

Autodelta, Alfa Romeo's competition arm, prepared the GTAm for the European Touring Car Championships. In 1970, the works won six of nine races, and the Dutch driver Toine Hezemans secured the European Driver's Championship. In 1971, the class was divided and a new minimum weight introduced, but Hezemans was able to retain the Championship.

Figures suggest that there were 40 GTAms built, although the confirmed number is closer to half that. Fifteen cars were supplied directly to Autodelta for their own use—the recorded works cars. A handful of cars were sold to privateers who commissioned Autodelta to upgrade them to GTAm specification. Three were exported to America and Angola, one to the Jolly Club in Italy, and this car, 1531231, to Luigi Cecchini of Lucca, on May 26, 1970, as confirmed by Alfa Romeo Autodelta. The remainder of the 40 or so produced is accounted for by privateers who bought parts from Autodelta and carried out conversions themselves.

This car debuted in the hands of Cecchini in the Copa della Collina in June, 1970. It suffered a minor incident, and there appears to be no racing history after this event. The Alfa then went to Spain and was eventually bought by the present owner in Sicily in 1986. It was subsequently restored over a period of four years to its original condition and features full Autodelta specs, being fitted with correct 2-liter fuel injection and twin-spark head. On completion of the restoration, the car was used in various historic competition events, including the Alfa day at Monza in 1990. It has been featured in a number of Italian publications in April, 1992, and December, 1996. The car was driven by Teodoro Zeccoli, an original works driver who wrote to the owner thanking him, and confirming the car was as it was when it originally raced and is "unbelievably fast."

Use since restoration has been limited to 60 miles and the car is reported to be in excellent condition. The car is eligible for the Tour Auto, Youngtimer series and a number of track events. It is offered for sale with a file containing a letter from Alfa Romeo, copy for the specification for the model, various photographs and the magazine articles the car was featured in.
