My favourite obscure spot is from 'Shaft in Africa' in which the coolest '70's private eye ever drives a 2000GTV (what else).
The plot obviously calls for some kids to steal the hubcaps and in true low budget blaxpoitation fashion the Director doesn't let the fact that 2000GTV's don't actually have conventional hubcaps stop him.
So the scene shows kids fiddling around with hubcaps clearly from a different car and Richard Roundtree shouting after them as they run away with the completely unnecessary hubcaps.
There is a murder comedy on Netflix just out that has a Giulia Quad chasing a Ferrari in a city on the French Riviera. It doesn't end well for the Alfa but the Ferrari doesn't get away either. Very well shot car chase.
This isn't it but it's an Alfa GTZ passing 25 cars at Laguna Seca. Sweet!
