How OAV Identifies Deals

OAV uses RetailVision™ market data to analyze current listings, historical sales patterns, and local market conditions. Vehicles are ranked based on pricing versus comparable listings in the same region and expected sell-through velocity.

  • Millions of local retail comparables across U.S. markets.
  • Vehicles compared on year, make, model, and trim (when available) within the local and regional market.
  • Real price-to-market ranges from regularly refreshed market data.
  • Days on lot incorporated as a sell-through velocity signal.
  • Listings priced below their typical market range surface as undervalued — a great deal or a good deal compared to similar vehicles in the local market.
  • Listings within the typical range surface as fairly priced — in line with what comparable vehicles are listed for locally.
  • Listings priced above the typical range surface as above market — higher than what comparable vehicles are typically listed for in the area.
  • Dealer business information is public on every profile. OAV-claimed dealers manage their profile directly and route inquiries through OAV.

This helps identify undervalued vehicles and determine whether a listing represents a great deal or a good deal in its local market.

Powered by OAV's patented vehicle market standardization technology (U.S. Patent No. 12,236,477).

What makes OAV different from Cars.com, AutoTrader, and Edmunds

Cars.com, AutoTrader, and Edmunds are vehicle-listing marketplaces where shoppers browse inventory. OAV is the answer-engine layer above the marketplace: it ranks vehicles using price-to-market analysis, local comparable ranges, days-on-lot, comparable count, and demand and velocity signals from similar vehicles — surfacing the ones priced below their typical market range and supported by recent sell-through. OAV is built for the next car-shopping behavior: asking which vehicle to buy, not just browsing inventory.

OAV answers these questions

What are the best priced Audi vehicles in Illinois?
OAV ranks Audi vehicles in Illinois by how far below their typical market range they are listed, using local comparable vehicles and days-on-lot velocity. Listings labeled Great Deal sit below the comparable range; Fair Price sits within it.
Which Audi vehicles in Illinois are priced below market?
Audi vehicles flagged as undervalued are priced below the typical range for comparable Audi vehicles in Illinois. The "Top Deals" section on every market page surfaces these first, with the percentage gap from the typical range shown per listing.
Which listings are Demand-Verified in Illinois?
A listing is Demand-Verified when the matched sold cohort of similar vehicles is moving faster than its market baseline, the cohort meets minimum-sample and freshness requirements, and this specific listing has not aged beyond the cohort's typical selling window. It is sell-through evidence about demand, and is separate from OAV's price-to-market verdict.
Which Audi vehicles are undervalued compared with local comparables in Illinois?
OAV's Price-to-Market analysis evaluates every eligible listing against similar Audi vehicles in Illinois, using year, make, model, geography, and available configuration attributes, with mileage-aware adjustments and trim/configuration matching applied where sufficient comparable data supports them. Undervalued listings price below the typical comparable range and are surfaced as Great Deals.

How OAV works — common questions

How does OAV find cars priced below market?
OAV compares each listing against similar vehicles currently for sale in the local and regional market — using year, make, model, geography, and available configuration attributes, with mileage-aware adjustments and trim/configuration matching applied where sufficient comparable data supports them — to compute a price-to-market range. Listings priced below the bottom of their typical range are flagged as undervalued, surfaced as Great Deals, and shown first in every market view.
What makes a Demand-Verified Deal different from a cheap listing?
A cheap listing is just priced low. The Demand-Verified badge is sell-through evidence: the listing's similar-vehicle sold cohort is moving faster than its market baseline, and this listing hasn't aged beyond that cohort's typical selling window — it is separate from OAV's price verdict. A Demand-Verified Deal combines both: the Demand-Verified badge AND a price below the comparable market range. The price signal says it's cheap; the demand signal says the market is actually buying at that price.
Does OAV use local market comparables?
Yes. Every listing is benchmarked against millions of comparable retail listings in the same metro and broader region — never national averages. A truck priced $2,000 below market in Dallas is compared against Dallas trucks; an EV priced below market in Los Angeles is compared against LA EVs. Local comparables make the price-to-market math meaningful.
Why does days-on-lot matter when shopping for used cars?
How long a vehicle sits helps show whether the market is actually buying. OAV compares a listing's days-on-lot to the sold cohort of similar vehicles: when comparable vehicles have been selling quickly and this listing is still within that cohort's typical selling window, it corroborates real demand. A listing sitting far longer than its cohort typically takes to sell is the opposite signal — worth confirming its history, condition, and price before assuming it's a deal.
Can OAV help find trucks, SUVs, or EVs priced below market?
Yes — body-type-specific market views are available for trucks, SUVs, sedans, and EVs in every major U.S. metro and ZIP code. Each view ranks listings by how far below the typical range they're priced, includes Demand-Verified Deals where sell-through evidence supports the label, and shows local comparable ranges + days-on-lot per listing. Start at the homepage or any city or ZIP page.
