New Sedans in Costa Mesa, CA
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.

How OAV Identifies Deals
OAV builds a comparable range for each vehicle from regularly refreshed dealer-advertised listings — same make, model and year range, trim where the data supports it. Where the evidence supports a verdict, a vehicle is rated by how its asking price compares to that range; days-on-lot and sell-through are separate demand signals, never inputs to the Price-to-Market verdict. When OAV evaluates a listing but the evidence does not support a verdict, the listing is Unscored.
- 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 is a separate demand signal, never an input to the Price-to-Market verdict.
- 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 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.
