The Acadia Denali gets rid of the cheap-looking black plastic and has body colored bumpers. It also has HID headlamps and a lot of chrome accents.
There is more room in this truck than a Tahoe so we felt it would suit our needs well. It can also pull a small trailer if needed.
We have three young children and the DVD entertainment system does a GREAT job of keeping them quiet on long drives. :)
GMC has a great reputation. We purchased the Acadia over the Traverse because it has more features and better styling.
