Maho: 'No, I am not letting you drive my tigers and panthers, they are too expensive to run.'
Ironically when Italy capitulated in 1943, Germany was well in the process of proving aid in helping to produce their own panther tanks as the M45/44... Though as actual vehicles were concerned, the Italians never saw anything larger than the Mark IV from their German allies.
They did get a good number of Pershing tanks during the cold war however...
