The Pontiac GTO is an automobile that was manufactured by American automaker Pontiac from the 1964 to 1974 model years, and by GM's subsidiary Holden in Australia from the 2004 to 2006 model years.
The first generation of the GTO was the first muscle car produced in the 1960s and the 1970s.
The Pontiac GTO is considered by some to have started the trend with all four domestic automakers offering a variety of competing models.
