Roma violenta (1975) - Car Chase Scene. Is the Alfa a Giulia or Berlina?

Hi folks -- Jonathan Summers suggested this film to me; it is a favorite chase of his. I find it absolutely terrific.the film is about a former detective  who is employed by a group of citizens to rid Rome of the widespread crime it is known for. The Alfa is the above scene is either a Giulia or Berlina. I do not know enough about these cars!
