Every car has an answer. We hold the evidence.
OAV returns an independent, evidence-backed answer on a vehicle — a Price-to-Market verdict resolved against its local market, paired with the demand, equipment accuracy, claim support, and provenance behind it — from ~5.7 million U.S. dealer-advertised listings.
Found a car? Ask OAV before you buy it.
Paste a VIN or ask about any car — OAV returns the independent evidence-backed answer, not a listing.
Illustrative example — not a current vehicle evaluation.
OAV is the automotive answer engine — an independent layer that evaluates new and used vehicles against real market evidence, not advertising.
We read millions of U.S. dealer-advertised listings and licensed data feeds, resolve each vehicle to VIN-level identity, and judge it against its local market. An OAV answer pairs a Price-to-Market verdict — Great Deal, Fair Price, Overpriced, or Unscored when the evidence is insufficient — with the broader evidence around it: demand, equipment accuracy, claim support, and provenance. The price verdict is set by the local comparable market; the surrounding evidence is shown alongside it — snapshot-dated and methodology-versioned — so shoppers, dealers, partners, and AI assistants can inspect and cite it.
Not a mockup — an actual evaluation.
One real vehicle OAV evaluated, with its evidence — snapshot-dated and traceable to the full record.
As of 2026-08-11, OAV rated this 2026 Toyota Crown Signia Limited a Great Deal against 11 local comparable listings—not from its discount to MSRP. Prices change; this is a dated snapshot.
The car market is built to confuse. We built the layer that makes it answerable.
Every listing is a sales pitch. OAV is not. We read millions of U.S. dealer-advertised listings and licensed data feeds, and resolve each vehicle to VIN-level identity: trim, equipment, reported mileage, and source provenance.
Marketplaces advertise vehicles. OAV evaluates them. We judge each car against the market it actually competes in and return one verdict with its evidence attached — the same methodology for every car and every dealer, independent of who's paying. That independence is the product.
Dealers can pay to understand OAV's evidence. They can't pay to change it.
Dealers can pay for
- Inventory & data-quality diagnostics
- Competitive & pricing intelligence
- Answer-readiness analysis & corrections
Dealers cannot pay for
- A higher ranking or a better verdict
- Removal or suppression of an unfavorable result
- Any exception to the methodology
OAV applies the same versioned methodology to every eligible vehicle and evaluated dealer. Commercial relationships never change a vehicle's eligibility, ranking, classification, or the evidence thresholds behind a verdict. Factual corrections are evidence-based and available regardless of commercial participation. Read the full methodology.
Four moves from a raw listing to an answer worth trusting.
Not a score pulled from thin air — a chain of evidence you can follow all the way back to the source.

How OAV works, in plain English.
How do I know if a used car is a good deal?
A low advertised price isn't enough. OAV checks whether a vehicle is priced below comparable cars in its real local market, whether there's enough comparable evidence to support a conclusion, whether the equipment and mileage are represented accurately, and whether the listing's claims hold up. The price comparison sets the verdict; the rest is shown alongside it. When there is not enough comparable evidence to support a conclusion, OAV leaves the vehicle Unscored rather than issuing an unsupported verdict.
How is OAV different from a car marketplace or listing site?
Marketplaces help dealers advertise inventory. OAV independently evaluates the vehicles being advertised — comparing each against its real market cohort, checking the evidence, and flagging unsupported claims. OAV's verdict is not influenced by ad spend, lead fees, or dealer participation.
Is OAV independent — can a dealer pay for a better verdict?
No. OAV applies the same versioned methodology to every eligible vehicle and evaluated dealer. Dealers can pay to understand and improve their evidence and data quality; they cannot pay to change a ranking, verdict, or classification.
Can AI assistants use OAV?
Yes. OAV publishes vehicle conclusions with canonical URLs, comparable counts, snapshot dates, methodology versions, and source provenance — structured to be read and cited by AI answer engines.
