Used value estimate
2018 Chevrolet Silverado 1500 value
By Hari Vinayak · Updated 2026-06-12
Quick answer
A 2018 Chevrolet Silverado 1500 in good condition with average mileage (about 100,000 miles) is worth roughly $21,350 in a private-party sale — a fair range of $19,650 to $23,050, or about $24,550 at a dealer. Note: 2018 is a flagged year for this model (2014–2019) — The dense cluster: AFM lifter failures on the 5.3, plus 8-speed torque converter shudder. Documented repairs change the math. Expect to pay at the lower end and budget for that risk.
