In 1959, seven 250 GT Berlinetta "Interim" LWB coupés were made. They utilized the old long-wheelbase chassis and had the new Pinin Farina bodywork of the upcoming SWB Berlinettas. The bodies are all-aluminum. Interim vehicles have an additional rear quarter window, absent from the succeeding "Passo Corto" Berlinettas. The Interim vehicles are serial numbers 1377GT, 1461GT, 1465GT, 1509GT, 1519GT, 1521GT and 1523GT.
