General Motors revealed the 2004 Pontiac Grand Prix, the ninth generation of the mid-size sedan. For 2004, GM has eliminated the base model SE. Customers can choose from the GT, GTP, and GTP with the Competition Group package. The Competition Group – or “Comp G” – option includes 17-inch wheels and Stabilitrak Plus, which expands cornering ability during high-performance maneuvers and inclement conditions. The car will be manufactured at GM’s Oshawa, Ontario assembly plant in Canada.
