GMC Terrain in Illinois
OAV.io analyzes millions of vehicle listings using RetailVision™ market data to identify vehicles priced below expected market ranges based on year, make, model, trim (when available), and comparable listings.
OAV helps determine if a vehicle is a good deal by comparing its price to similar listings within its supported comparable range. Sell-through is separate Demand-Verified evidence, not part of the price verdict.
Independent market evidence — no dealer pays for inclusion or ranking, no editorial curation, only measured data from live listings.

How OAV Identifies Deals
OAV uses RetailVision™ market data to analyze current listings, historical sales patterns, and local market conditions. Vehicles are ranked by how their asking price compares to comparable listings; days-on-lot and sell-through are shown as separate demand signals, never inputs to the price-to-market ranking.
- Millions of retail comparables across U.S. markets.
- Vehicles compared on year, make, model, and trim (when available).
- Real price-to-market ranges from regularly refreshed market data.
- Days on lot shown as a separate demand signal (Demand-Verified), not a price-to-market ranking input.
- Listings priced below the comparable-range floor by at least OAV's minimum-gap margin surface as Great Deal — a great deal compared to similar vehicles currently for sale.
- Listings priced within the comparable range, or below the floor by less than that margin surface as Fair Price — fairly priced, in line with what comparable vehicles are typically listed for.
- Listings priced above the comparable range surface as Overpriced — above market, higher than what comparable vehicles are typically listed for.
- Dealer business information is public on every profile. OAV-claimed dealers manage their profile directly and route inquiries through OAV.
This helps identify which listings are a great deal relative to comparable vehicles — OAV's Great Deal verdict — and shows the evidence behind every rating.
