| 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 |

| 2008 | 4dr SUV 275-horsepower 3.6L V6 6-speed shiftable automatic AWD |
Since this is our family hauler, it needed to accommodate 5 people, with enough space between 3 kids to keep long trips bearable. Adults can sit comfortably in the third row. see full GMC Acadia review |

Best 3rd row leg room in its class. Smart slide seats provide easy access to 3rd row see full GMC Acadia review |

3rd row is big enough for adults, leg room & head room, comfortable bench seat; 2nd row captains chairs were an option that I chose; easy to get around 2nd row and into 3rd row. I believe the Acadia was 11" longer than the Toyota Highlander. see full GMC Acadia review |

Have taken this car on long trips, 14 hours of driving, multiple days in a row. The front seats are ok but not very comfortable. It's even tiring for the passenger. see full GMC Acadia review |
