Add your own review or comments

By Larry Edsall

Overview

The GMC Sierra is all-new for 2007, redesigned from the ground up. The new Sierra is built on a new platform, stiffer than before for better ride and handling. The exterior styling is all new and a new interior offers the buyer many more options, including a choice of two dashboard styles.

The 2007 GMC Sierra will be offered in a Denali version, which makes for a comfortable, luxurious, and highly capable truck. A Sierra Denali can handle business and family affairs as well as perform serious towing and hauling duties. The Sierra Denali offers the same sort of exclusive content as GMC's upscale Yukon Denali sport utility.

Note that until production of the new truck ramps up, GMC dealers will be selling old-style Sierras as 2007 GMC Sierra Classic models. These are not to be confused with the all-new 2007 version.
