The rear glass appears to wrap around because of the glossy black pillars, the current grill is far nicer than the old chrome bar design, and the fender bulges are nice. Also like the headlamp design and the way they slant down to the inner edge.
The 2002 model I had previously was a great truck. Traded it in with 94,000+ miles, and the only out of warranty repair I had to make (other than maintenance) was a fan clutch. That truck was completely reliable and was a joy to own.
So far this truck gives me no reason to believe it will be any less reliable than my 2002. It tows just as well, and there seem to be many strides from GM to make it better in other areas. So far, so good.
