What makes OAV different from traditional car-listing sites

Traditional vehicle-listing marketplaces are built for shoppers to browse inventory. OAV is the answer-engine layer above the marketplace: it evaluates vehicle asking prices with Price-to-Market against comparable listings and shows the market evidence behind each verdict. Days-on-lot and sell-through from similar vehicles are separate demand evidence, never inputs to the Price-to-Market verdict. OAV is built for the next car-shopping behavior: asking which vehicle to buy, not just browsing inventory.

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.

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

How OAV works — common questions

How does OAV find cars priced below market?

OAV compares a listing's asking price against similar vehicles currently for sale — using year, make, model, geography, and available configuration attributes, with trim/configuration matching applied where sufficient comparable data supports it — to compute a price-to-market range. Mileage is never used to select comparables or adjust their prices. OAV withholds a verdict when mileage looks unreliable, or when higher-than-typical mileage, not a market discount, better explains a lower price. Over 120,000 miles, OAV still publishes Overpriced but withholds Great Deal and Fair Price: comparable cars usually have fewer miles, which can make those two verdicts misleading. Where OAV publishes a verdict, a listing priced below the comparable-range floor by at least OAV's minimum-gap margin is rated Great Deal; one priced within the comparable range, or below the floor by less than that margin, is Fair Price.

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 cohort of similar vehicles whose listings recently came off the market is leaving the market faster than its market baseline, and this listing hasn't been listed longer than that cohort's typical time on market — it is separate from OAV's price verdict. A Demand-Verified Deal combines both: the Demand-Verified badge AND a Great Deal verdict from Price-to-Market (priced below the comparable-range floor by at least OAV's minimum-gap margin). The price verdict establishes where the asking price sits relative to OAV's supported comparable range. The Demand-Verified signal measures whether the matched cohort's listings are coming off the market faster than its market baseline and whether this listing has been listed longer than that cohort's typical time on market — it does not show that buyers are paying this listing's asking price. While OAV re-validates the sell-through claim, the badge is withheld on every listing and no Demand-Verified Deals are being labeled.

Does OAV use local market comparables?

Yes — local-first. OAV starts with comparable retail listings in the same metro and broader region, and widens the comparison set only when local inventory is too thin to support a reliable range. A truck in Dallas is compared against Dallas-area trucks where the local market supports it; an EV in Los Angeles against LA-area EVs. This local-first approach makes the price-to-market math meaningful.

Why does days-on-lot matter when shopping for used cars?

How long a vehicle sits is a demand signal about its cohort, not proof that buyers are paying this listing's price. OAV compares a listing's days-on-lot to how long listings for similar vehicles stayed on the market before coming off it (not always a sale): when those listings have been coming off the market quickly and this listing has not been listed longer than is typical, it corroborates real demand. A listing sitting far longer than its cohort's typical time on market 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 — OAV has body-type market views for trucks, SUVs, sedans and EVs in major U.S. metros and ZIP codes. Each listing links to its vehicle page. Start at the homepage or any city or ZIP page.
