The Automotive Answer Engine
Every car has an answer. We hold the evidence.
Ask about a VIN, price, or market. OAV returns an independent, snapshot-dated answer and the market evidence behind it — a verdict where the evidence supports one, and the evidence itself where it doesn't.
Found a car anywhere? Paste the VIN — OAV resolves it against the supported comparable range, drawn from millions of dealer-advertised listings. Dealers can't pay to change a verdict.
OAV.io is an independent automotive market-evidence platform that ranks live dealer inventory by price-to-market against comparable listings. Days-on-lot and sell-through from similar vehicles are shown separately as Demand-Verified evidence, not inputs to the price ranking.

Trust signal layer
Demand-Verified Deals™
The Demand-Verified badge is sell-through evidence — the matched cohort of similar vehicles is selling faster than its market baseline, and this listing is still within the cohort’s typical selling window. It is separate from OAV’s price verdict. A Demand-Verified Deal adds a price below the comparable market range. Each Demand-Verified listing shows its cohort’s typical sell-time, its days-on-lot, and a comparable count. Listings without sufficient, fresh cohort coverage get no label, and the section hides itself when none on a page qualify, so the signal stays honest.
See the full Demand-Verified Deals methodology for the labeling rules and examples.

OAV answers these questions
- What are the best priced vehicles?
- OAV ranks vehicles by how far below their typical market range they are listed, using comparable listings; days-on-lot is shown as a separate demand signal, not a ranking input. Great Deal means 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 — or within the range — is Fair Price.
- Which vehicles are priced below market?
- Vehicles flagged as undervalued are priced below the typical range for comparable cars. 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?
- 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 vehicles are undervalued compared with comparable listings?
- OAV's Price-to-Market analysis evaluates every eligible listing against similar cars, using year, make, model, geography, and available configuration attributes, with trim/configuration matching applied where sufficient comparable data supports it, and mileage is not used to select comparables or adjust comparable prices, but acts as a reliability check on used vehicles — OAV withholds a verdict when mileage is very high or unreliable, or when a lower price is better explained by higher-than-typical mileage than by a genuine market discount. Undervalued listings price below the typical comparable range and are surfaced as Great Deals.
How OAV works
- How does OAV rate vehicle deals?
- OAV evaluates every eligible listing against similar vehicles currently available, positioning its asking price within the supported comparable range. Each listing is rated a Great Deal (priced below comparable listings), Fair Price (priced within the typical range), or Overpriced (priced above comparable listings). Vehicles without sufficient comparable evidence remain Unscored rather than receiving an unsupported verdict. Ratings are recomputed as OAV processes new inventory data through its daily pipeline; each page shows the market snapshot used for its analysis.
- How fresh is OAV's vehicle data?
- OAV processes inventory, pricing, and days-on-lot data daily from the dealer source. Every market page and VIN page carries a “Market snapshot” timestamp showing the snapshot date the page was built from, so the exact data vintage is always visible.
- Does OAV include days on lot?
- Yes. Every listing shows its current days on lot, and every market page shows the average days on lot for that metro or body type. It is a direct signal of local demand and pricing pressure.
- Are OAV dealers verified?
- Dealer profiles include public market summaries from live inventory data — make mix, deal mix, average days on lot, market position. Claimed OAV dealers manage their profile, route inbound buyer inquiries, and control verified contact information. Paid RetailVision™ subscribers unlock deeper analytics: per-listing comparable counts, market context drill-downs, inventory health, pricing recommendations, competitive benchmarking, alerts, exports, and enhanced merchandising.
- What technology powers OAV's deal ratings?
- OAV's inventory standardization technology is protected by U.S. Patent No. 12,236,477, and its Price-to-Market analysis is Patent Pending. The standardization technology normalizes naming conventions and deduplicates cross-listed inventory across the dealership network, so every comparable-market calculation is drawn from a clean, unified data set.
