A type of car roof characterized by a removable center section. The term first came into being with the 1966 Porsche 911 Targa Top, which was advertised as a "convertible with a roll bar." It is named after the Targa Florio, a famous road race in Sicily from 1906-1977.
Salesman: "Would you like your Porsche 911 with a sunroof or Targa top?"
