I bought this vehicle for commercial use and it has been pretty good. Problem areas have been the fuel injectors (replaced under warranty), and faulty gauges. After almost 3 years of ownership, the truck still looks good and drives very carlike. I chose a Duramax for it's smoothness over the Ford and Dodge diesels. My truck has the 12,000 GVW package and I have not been able to bottom out the suspension, in spite of my best efforts!
Exterior design, controls, engine/tranny.
Gauges that actually work in all temperatures, standard center armrest.
