Data sources, methodology & limitations
- Snapshot date: this page reflects the August 2026 national sweep. Figures refresh with one new snapshot per month.
- Asking prices: medians and counts are derived aggregates computed from licensed live-listing data covering U.S. dealer inventory (listings deduplicated per sweep). They are advertised prices — the out-the-door number a buyer negotiates is typically different.
- Buyer-paid figures: sourced exclusively from verified buyer-submitted deal sheets, labeled with model year and shown only when the sample is large enough. Asking data and paid data are never blended.
- Scope: national aggregates — local markets can sit meaningfully above or below these medians. For used Sierra 1500 values broken out by model year, see the GMC Sierra 1500 depreciation curve.
