Havana is the capital city of Cuba, where Michael Corleone went in 1958 to discuss business with Hyman Roth of Miami. In Havana, Michael's vehicle of choice was a Mercury Montclair. At this time, war was raging between the forces of President Batista and revolutionary Fidel Castro.
This night also brought down Batista's regime, as he abdicated and fled the country. Michael Corleone also left that night, as did his brother Fredo, who feared for his life after unwittingly betraying his brother.
