2008 Pontiac Grand Prix Seat Room and Comfort: Pros
YearBody/PowertrainComment
2008 4dr Sedan 303-horsepower 5.3L V8
4-speed shiftable automatic FWD
Front of the GXP is great - heated leather seats, plenty of seat adjustments, and the controls are all pointed at the driver. Even on a 20 hour trip, I had no issues with discomfort. see full Pontiac Grand Prix review
2007 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD
Front seats are nicely bolstered and are adjustable in every aspect. see full Pontiac Grand Prix review
2007 4dr Sedan supercharged 260hp 3.8L V6
