This is my first domestic vehicle. This truck has wonderful fit and finish, and has appoinments similar to those you mind find in European cars. The power is impressive, though it seems a bit sluggish from a stoplight or in a passing lane. The poor MPG is well documented. I drove it from LA to Monteray (roughly 400 miles) at 75 with the cruise control...and still only averaged 14mpg. All of the luxury features are nice, and made well. Bluetooth is a feature this vehicle is missing, and GM has no real excuse for not equipping it on a $50+ truck.
The styling, the interior comfort, and the handling equal to that of a much smaller vehicle all make this a fun car to drive.
MPG is horrible (12-14 in most conditions). Lack of Bluetooth in a vehicle already equipped with microphone and integrated phone. GM and OnStar work excluslivly with Verizon to link the cars phone with a personal account...should think about adding other major carriers.
