Manufacturer MSRPReference

$87,425

This vehicle $77,425 · $10,000 (11%) 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.

About This 2026 GMC Sierra 2500HD

Listing updated: Sep 23, 2026

Listed by a franchise dealer in Bay City, TX · On lot for 17 days · VIN verifiable at NHTSA

This new 2026 GMC Sierra 2500HD AT4 is listed at $77,425 by reliance gmc in Bay City, TX 77414. It has 16 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is Silver. It features a 4WD drivetrain with a 6.6L V8 engine and Automatic transmission.

OAV's independent, evidence-backed Price-to-Market analysis rates this vehicle as a Great Deal — priced below the comparable-range floor by at least OAV's minimum-gap margin. Based on 10 comparable listings matched to this vehicle, the estimated market range is $79,014 to $83,698. The comparable range in TX is $79,014 to $83,698. These comparisons match year, make, and model, using trim where the data supports it. OAV does not adjust comparable prices for mileage — every price shown is the real advertised price. On used vehicles, mileage can still cause OAV to withhold a verdict — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than call it a deal it can't support.

This vehicle has been on the lot for 17 days.

Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 23, 2026. The comparable band (patent pending) is the input; ptm-verdict-v1 is the versioned OAV rule set that turns it into this verdict.

Market context

This listing is part of OAV's broader Bay City, TX 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 Dealpriced below the comparable-range floor by at least OAV's minimum-gap margin; a smaller gap under the floor is Fair Price.
  • Fair Pricepriced within the comparable range, or below the floor by less than that margin.
  • Overpriced — priced above the typical range for comparable vehicles.
  • Unscored — OAV withholds a verdict when the evidence cannot support one: too few or too widely spread comparables, a price it cannot validate, a branded or salvage title, or mileage that would distort the comparison. The listing stays visible; only the rating is withheld.

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.
