Passport International Automobiles (PIA) was a Canadian car dealership network owned by General Motors.

It sold vehicles from Isuzu and Saab as well as its own branded Passport Optima, a Korean (Daewoo) made badge engineered Opel Kadett E, starting in model year 1988.

General Motors' Geo import brand was introduced in the United States at about the same time.

GM's new, import-fighting Saturn division chose Passport to sell its new car beginning in mid-1992.

[1] General Motors Canada, however, changed its branding strategy in 1991 and disbanded the Passport division.
