Across 20,104 listed GMC Sierra 1500s nationwide, the average markup is -$2,228 vs MSRP and 97% are listed at or below sticker, with a median advertised price of $68,735. Updated daily.
The Sierra 1500 is GMC's half-ton — mechanically Silverado's twin (same GM platform, the same 2.7L Turbo, 5.3L and 6.2L V8s and 3.0L Duramax diesel, the same MultiPro tailgate) but positioned upmarket, with the Denali sub-brand doing the heavy lifting on both image and volume.
Trims. Pro and SLE anchor the fleet-and-value end; Elevation is the blacked-out street trim; SLT is the volume retail-luxury trim; AT4 and AT4X are the factory off-road trims (AT4X adds front and rear lockers and a proper suspension); Denali and Denali Ultimate are the luxury flagships that define the brand.
Sierra discounts noticeably deeper than its Silverado twin. Most listings sit at or below MSRP; the median lands right at sticker, but the average discount is meaningfully larger because the Denali and Denali Ultimate trims see big dealer cuts to move higher-priced inventory. The deepest discounting turns up in Idaho, Connecticut, Oklahoma, Minnesota, and Arizona. Texas and Florida hold the largest inventory. If you want the Silverado's mechanicals with a nicer interior, a discounted Denali frequently lands in the same money as a loaded Silverado High Country.
