Design Notes Lite: 2007 GMT900s
Up front, things looked a little different, at first, but I couldn’t find much that didn’t line up. It looks like a little bit of fine-tuning took place. This is the same model from early 2004.
Below, in the gray color, is a production 2007 Sierra.
Below is a zoomed in picture of the reddish model’s front end. I’m not sure what it is but something looks different.
The model shown in these last two pictures was labeled a Heavy Duty and were dated June 18 of 2004.
The headlights on this model appear to have involved a lot of intricate sculpting.
There are much larger versions of these pictures in the gallery, plus some extras of the production models.
