The Pontiac Grand Am began in 1973 on the A-body. The A-body Grand Am was cancelled in 1980.
1985
The Pontiac Grand Am was reintroduced as a compact car introduced by GM in 1985. It sat on the "N" platform, along with its siblings the Buick Somerset (Buick Skylark in 1987) and Oldsmobile Calais (Oldsmobile Cutlass Calais in 1987).
1992
In 1992, the GM N platform was redesigned, resulting in a newer looking Pontiac Grand Am. The last year of this design of the Grand Am was in 1998.
1999
In 1999, the Grand Am was redesigned once again, with its only compact sibling being the Oldsmobile Alero. (The Chevrolet Malibu and Oldsmobile Cutlass sat on the "N" platform as mid-size cars.) The Grand Am sedan was discontinued beginning in 2005; the coupe will most likely be dropped beginning in 2006, with the entire Grand Am line being replaced by the Pontiac G6, which sits on the GM Epsilon platform.
2005
In 2005, the Grand Am continued on in fleet sales while the G6 replaced it in the Pontiac lineup. Initially available only as a V-6 sedan, the G6 lineup will be expanded for the 2006 model year to include a 4-cyl model, a fastback coupe, and a 2-dr hardtop convertible. See Pontiac G6.
