Full 2000 GMC Sierra 1500 Review
What's New for 2000
After a complete redesign last year, GMC's Silverado-based pickup finally gets a fourth door on the extended cab. There's also more power on tap from the 4.8- and 5.3-liter engines, increased trailer ratings and standard programmable automatic door locks. New factory appearance items, such as wheel-lip flares and a soft tonneau cover, are now available on some models.
