Bought another without question or reservations. Good handling and power to pull just about anything within it's legal limit and more. With the 2006 model there is no need to keep pouring in the DEF either so no mess from the spill of corrosive material. That Duramax engine and the Allison transmission are bullet proof they say and my experience holds that to be true. No rust either but the paint as with other GM products does tend to chip a bit. Just a good all round stylish reliable vehicle.
