None were found in Italy, as Italian taxation system and the industry structure forced manufacturers to design every part in-house; a daunting task for small companies like Maserati. Thus the 3500 GT alongside Italian Weber carburettors and Marelli ignition, used many British-made components such as a Salisbury rear axle, Girling brakes and Alford & Alder suspension parts.
In Italy, no such vehicles were produced due to stringent tax policies and industry regulations that required manufacturers to design all components in-house. This was particularly difficult for small companies like Maserati. Consequently, the 3500 GT incorporated many British-made parts including a Salisbury rear axle, Girling brakes, and Alford & Alder suspension components alongside Italian Weber carburettors and Marelli ignition.
