New or Significantly Altered Models

2004 Pontiac Grand Prix
The Grand Prix has been reworked for 2004. Still FWD and basically the same size, the new Grand Prix features new packaging inside and out. The base model GT has a 200hp V6. The supercharged-GTP model is good for 255hp. A Comp G package is available for the GTP that improves the handling and adds a paddle shifter.
2004 Pontiac GTO
The new GTO is a rebadged Holden Monaro from Australia. What's really news is the 350-bhp, 5.7L V-8 powering the rear wheels. Enthusiasts will overlook the innocuous styling in favor of the outstanding powertrain.
