2025 GMC Sierra 2500HD AT4

Listed by a franchise dealer in Natchez, MS · On lot for 116 days · VIN verifiable at NHTSA

This used 2025 GMC Sierra 2500HD AT4 is listed at $62,500 by auto group south in Natchez, MS 39120. It has 63,623 miles on the odometer (dealer-reported, not independently verified by OAV). 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 Unscored. This vehicle has higher mileage than is typical for its age, so its lower price isn't enough on its own to establish a like-for-like market discount — OAV withholds a verdict rather than call it a deal.

This vehicle has been on the lot for 116 days.

Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 22, 2026. The patented comparable band is the input; ptm-verdict-v1 is the versioned OAV rule set that turns it into this verdict.

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 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.
