Better 2nd & 3rd row comfort than the Honda Minivan (this is to be a daily driver for a family with 4 kids under 10) see full GMC Acadia review |

Power seats have versatile adjustments. Thigh support is better than some compact SUVs that I compared. Tilt and telescoping steering wheel is flexible for driving position. see full GMC Acadia review |
