If you want power, the Sierra's got it. But if high-quality materials and solid build quality are also a priority, you might want to check the offerings from Ford and Toyota, as well.

what's new

Reliability improvements for all Vortec V6 and V8 engines top the list of changes this year. Consequently, oil-change intervals have been extended to 7,500 miles. A traction assist feature is now available on two-wheel-drive V8 automatics, thanks to a new electronic throttle control system. Factory-installed OnStar, GM's mobile communications and security system, has been made standard with the SLT trim level. New this year is a 325-horse, all-wheel-drive performance version called the C3.
