How this deal is rated

OAV compares this 2021 GMC Terrain against similar vehicles currently available for sale — same make, model, and year range, using trim where trim data supports it. OAV does not adjust comparables for odometer; on very high-mileage vehicles it withholds a verdict rather than overstate a discount the odometer explains. 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.
