The Silverado 1500 is about as classic a work-truck it comes. AutoPacific 2007 Vehicle Satisfaction Award Winner. It is nicely equipped with features such as 4-Speed Automatic with Overdrive and Vortec 5.3L V8 SFI.

New Car Test Drive said it was "...among the smoothest riding and quietest of all full-size pickups, t any comparative price point. We think it's one of the best choices available..."
