This artisan-made sports car was built after the Second World War in Rome by Placido Prete (the P in its name) by installing a 6C 2300B Alfa Romeo engine (the A in its name), with a Regia Marina type dry sump system bored for 2442c, on a tubular chassis of unknown origin using parts of Maserati origin (the M in its name). Prete wanted to add his name to the car so assembled designing the coat of arms with three initials AMP over the background of the Colosseum.

It is believed that the Roman pilot and mechanic Placido Prete bought a Maserati 4 CL (it seems the chassis No. 1566) of 1939, which had suffered serious damages at the engine, by the Neapolitan driver Giovanni Rocco. The acquisition cost was very low, since finding a replacement engine would not have been a simple matter. Maserati 4 CL, already in 1939 had been shown to have serious problems in the race and the Maserati decided to replace it with the evolution “4CLT“ created on a tubular frame.

Placido Prete decided to turn it into a “sports version type“ to compete in races of that category and especially at the Targa Florio and Mille Miglia. The car underwent a complex transformation. It was fitted with a new engine from an Alfa Romeo 6C 2300, with displacement increased to 2,500 cc., processed to achieve the power of 200 HP, with a top speed of 240 Km/h and a different Powertrain transmission. The chassis was redone with trellis tubes, leaving unaltered the original system of suspension, differential and brakes of Maserati.

Given over to Giovanni Rocco, it made its debut on the Pescara circuit in 1948 and managed to finish the race (no small feat in those days). Rocco then with Prete attempted the Targa Florio-Giro di Sicilia in 1949, achieving an overall third. But at the Mille Miglia of that year, the Rocco-Sorrentino crew was forced to withdraw before the check-point at Pescara, even thought at the check-point in Rome they had been sixth. In 1950 Francesco Santovetti who buy the car from Prete arrived third in Vermicino–Rocca di Papa of 1952. In 1953 led by Scarlatti was the second at the Coppa dei due Laghi.

Throughout its history, the car underwent different variations of bodywork, from two to four lighthouses, with wrap-around mudguards, partial, or missing, with the air intake on the bonnet or without, with or without windshields for the passenger.

The AMP is now recorded both in the Alfa Romeo and Maserati registers. Some few sources indicate the AMP as built by mechanical Tino Martinoli and financed by Prete.
