About This 2025 GMC Sierra 2500HD

Listing updated: Sep 23, 2026

Listed by a franchise dealer in Newcastle, ME · On lot for 185 days · VIN verifiable at NHTSA

This used 2025 GMC Sierra 2500HD AT4 is listed at $65,750 by key chrysler dodge jeep ram of newcastle in Newcastle, ME 04553. It has 26,118 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is Gray. 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 Fair Price — priced in line with the supported comparable range. Based on 120 comparable listings matched to this vehicle, the estimated market range is $64,995 to $76,950. The comparable range in ME is $67,999 to $68,898. 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 185 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 Newcastle, ME 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 2025 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.
