The Pontiac Sunbird (also known as the Pontiac J2000 and Pontiac 2000) is a model line that was manufactured and marketed by Pontiac from the 1976 to the 1994 model years. Loosely deriving its name from the Pontiac Firebird, the Sunbird was introduced as the eventual replacement for the Pontiac Astre, replacing it entirely in 1978 as the smallest Pontiac (the later T1000 was slotted below it in size).
