About This 2020 GMC Terrain

Listing updated: Sep 15, 2026

Listed by an independent dealer in Macomb, MI · On lot for 147 days · VIN verifiable at NHTSA

This used 2020 GMC Terrain SLE is listed at $11,000 by milano auto sales in Macomb, MI 48042. It has 120,957 miles on the odometer (dealer-reported, not independently verified by OAV). The exterior color is White. It features a 4WD drivetrain with a 1.5L I4 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 66 comparable listings matched to this vehicle, the estimated market range is $10,995 to $23,995. 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 147 days.

Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 15, 2026. The patented comparable band 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 Macomb, MI suvs 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 2020 GMC Terrain 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.
