You can thank the Coca-Cola Company for attaching the term "classic" to a product that should actually be termed "old." The latest company to grab hold of this scheme is GMC. With the arrival of the all-new Sierra, the previous model forgoes mothballing to become the 2007 GMC Sierra Classic. A capable pickup truck by all measures, the Sierra Classic continues to offer a full range, including 1500, 2500 and 3500 models in Regular Cab, Extended Cab and Crew Cab configurations. Despite the Sierra Classic's age, it can still pull, haul and luxuriate with the best new rivals from Dodge, Ford and Toyota.
