Why the wide range? Price depends mostly on configuration and mileage — see below. This spread covers the middle 96% of asking prices: we exclude the cheapest and priciest 2% to reduce the influence of extreme values. This does not verify title status or guarantee that every erroneous listing is excluded.

Where these specifications come from
Specifications combine decoded VIN data, including NHTSA vPIC , with inventory records. If decoding does not identify a trim, a recorded inventory trim may be shown. VIN patterns do not confirm every installed option.
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 1998 GMC Sierra prices range from $2,764 to $22,679?
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 $4,775 and $14,248 — see the mileage and trim breakdowns above for where a specific vehicle lands.
Is $10,656 a good price for a 1998 GMC Sierra?
$10,656 is the market average as of October 1, 2026. The $11,444 median is a comparison point, not a deal rating. Compare the same trim and mileage band, and check condition, equipment and vehicle history.
How many 1998 GMC Sierra are for sale right now?
20 in total, nearly all pre-owned. Counts refresh daily from live dealer inventory.
Is this the trade-in value or private-party value of my 1998 GMC Sierra?
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 20 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.
