Redesigned from the ground up, the GMC Sierra is all new for 2007, although the previous generation model referred to as Sierra Classic is also still offered. The new Sierra is built on a stiffer platform, which provides better ride and handling characteristics than its predecessor. Exterior styling has also been revamped, and a new interior offers consumers more options. Better fuel economy and improved towing capacity are among the new model’s other benefits.
