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 24, 2026, 05:00 UTC. 9 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.

Counts describe observed VINs in our database, not factory production totals. Prices are median asking prices from qualifying U.S. listings, not original MSRP. Check the vehicle’s build sheet for exact equipment.

Frequently asked questions
Why do 2026 GMC Sierra HD prices range from $61,490 to $107,909 in Washington?
The spread comes down to configuration and mileage: higher-mileage, base-configuration examples sit near the low end, while low-mileage and premium configurations reach the top. Half of all listings fall between $87,120 and $99,425 — see the mileage and trim breakdowns above for where a specific vehicle lands.
How much should mileage change the price of a 2026 GMC Sierra HD?
Across the lowest- and highest-mileage groups, asking prices differ by roughly $2,700 per 10,000 miles. These groups contain different vehicles: this is not a same-trim adjustment or a forecast for one car. Compare the mileage and trim tables, then check condition, equipment and vehicle history.
Do GMC Sierra HD prices in Washington differ from the rest of the country?
Yes. The average in Washington is $90,691, which is $7,739 above the national average of $82,952. Local supply, demand and transport costs all play a part.
How many 2026 GMC Sierra HD are for sale in Washington right now?
207 in total: 196 new (averaging $90,924) and 11 pre-owned (averaging $86,542). Counts refresh daily from live dealer inventory.
Is this the trade-in value or private-party value of my 2026 GMC Sierra HD?
These figures describe dealer asking prices, not trade-in offers, private-party sale values or completed sale prices. Use them to compare advertised vehicles. To find out what a buyer or dealer would pay for your car, request an offer that takes its mileage, condition, equipment and history into account.
How we calculate these prices
We track 207 active listings for this vehicle across dealer sites in Washington, 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.
