GMC's 2000-06 full-size Sierra has powerful, efficient engines and an inviting interior, but expect a stiff, choppy ride.
A 2007 redesign brought more responsive handling and improvements to the ride, but the powertrains still aren't as refined as some competitors'.
High-end interiors have attractive fit and finish -- all have simple controls.
Fuel economy from the 5.3-liter V8 and six-speed automatic are decent, and its crash test scores are improved over previous versions.
Cabin access is easy, while towing and payload capacities are generous.
