What these prices mean
Only catalog listings with photos are included. Trim names do not verify equivalent equipment. Prices are asking prices, not completed sales. Alternatives share the body style and class of the source model; the nearest model years are used when the same year has too few listings. Price differences are not a valuation adjustment or guaranteed savings.
Snapshot: September 13, 2026, 19:00 UTC. 11 source listings excluded by statistical price screening; this does not verify that every deposit or payment ad has been removed.
VehiSales opens in a new tab with the model, year and known mileage range. Confirm trim, fuel, drivetrain, condition and location on VehiSales; its live inventory may differ.
2018 GMC Sierra 1500: a fair price for your mileage

Is this the trade-in value or private-party value of my 2018 GMC Sierra 1500?

How we calculate these prices
We track 19 active listings for this vehicle across dealer sites nationwide, updated every day. Average and median are computed from real asking prices on live listings. We exclude the top and bottom 2% of prices to reduce the influence of extreme values. This does not verify title status or guarantee that every erroneous listing is excluded. Prices reflect dealer asking prices — not final sale prices — and exclude taxes, fees, and incentives. Trim and mileage move the price more than any other factor; see the breakdowns above.
