Quick answer
A 2023 GMC Sierra 1500 in good condition with average mileage (about 37,500 miles) is worth roughly $32,350 in a private-party sale — a fair range of $29,750 to $34,950, or about $37,200 at a dealer. 2023 is not on our years-to-avoid list, so condition, history, and maintenance matter more than the model year here.

Compare the best and worst Sierra 1500 yearsWhat to check before you pay
- AFM/DFM lifter collapse (5.3/6.2) — cold ticking, misfires, check-engine history
- 2014–2019 8-speed: torque converter shudder ('Chevy shake') — GM's fluid change helps; ask if it was done
- AC condenser failures, especially 2014–2018 — confirm cold AC
