This vehicle $80,089 · $601 (1%) below MSRP

MSRP is the manufacturer's suggested retail price, shown for reference only. OAV rates new-car deals by how far below the supported comparable range a vehicle is priced (see OAV's market comparables / MRP and sold-price value / TRV) — not by discount from MSRP, because dealer-supplied MSRP is not independently verified. The advertised price is set by the dealer and may require financing, rebates, trade-in, or other qualifications, and excludes taxes, fees, and dealer add-ons — confirm the out-the-door price with the dealer.

Market context

This listing is part of OAV's broader Bozeman, MT trucks market analysis. OAV compares vehicles by local and regional price-to-market ranges and comparable count; days-on-lot and demand signals are shown separately, not as verdict inputs.

How this deal is rated

OAV compares this 2026 GMC Sierra 2500HD against similar vehicles currently available for sale — same make, model, and year range, using trim where the data supports it. OAV does not adjust comparable prices for mileage; on used vehicles it withholds a verdict when mileage would distort the comparison — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than overstate a deal. Based on where this listing falls in that comparable set, it is rated:

  • Great Deal — priced below the comparable-range floor by a meaningful margin (OAV's minimum-gap rule); a listing below the floor by less than that margin is Fair Price.
  • Fair Price — priced within the expected range for comparable vehicles.
  • Overpriced — priced above the typical range for comparable vehicles.

Listings show OAV's PTM-derived deal quality and live market context. OAV-claimed dealers manage their listing profile and route buyer inquiries directly. Paid OAV partners can surface additional verification signals, but commercial participation never changes a listing's Price-to-Market verdict, eligibility, ranking, or confidence.
