Used GMC Sierra 1500
Full-size half-ton · 19 listings · max towing 13,300 lb · max payload 2,240 lb
The GMC Sierra 1500 on the used market
GMC's upscale variant of the Chevy Silverado 1500. Same chassis, same powertrains, same body shell — but optioned heavier (Denali, AT4, AT4X) and finished more upscale. The MultiPro tailgate (2019+) is a genuinely useful innovation.
Used Sierras run 5–10% above equivalent Silverados in price. AT4 and Denali trims hold value harder than equivalent LTZ/High Country Silverados.

Buying a used GMC Sierra 1500 — what to know
The Sierra 1500 sits in the full-size half-ton segment, where competition is fierce and used pricing varies widely by configuration, mileage, and region. The single biggest variable on used pricing is powertrain — diesel-engined trucks of any year typically command a 15–30% premium over equivalent gas trucks, even after accounting for the higher fuel cost per mile. Use the year-by-year breakdown above to confirm which powertrains were even available in the model year you are shopping.
Trim level matters next. The trim ladder for the Sierra 1500 runs from work-spec base trims (vinyl seats, rubber floors, manual windows on older years) up through luxury-class top trims with leather, large infotainment, advanced driver assists, and air suspension. The depreciation curve on top trims is steeper than on mid-range trims, which makes 4–6 year old top-trim trucks an unusually strong used value. A 5-year-old top-trim Sierra 1500 often costs less than a new mid-trim version with comparable mileage and far less equipment.
Mileage matters but mileage type matters more. A high-mileage Sierra 1500 that lived a highway-commuter life is often a better long-term bet than a low-mileage truck that sat in city traffic and short trips its whole life. Ask the seller about usage patterns. Get the answer in writing if it influences your offer. And whatever the seller tells you, verify with a third-party pre-purchase inspection before signing.
