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, trim, mileage, and condition signals — 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 one that's priced low. A Demand-Verified Deal is priced below market AND backed by sell-through evidence — the listing's days-on-lot relative to similar vehicles tells us whether the local market is actually buying at that price band. Combining the price signal with the demand signal separates real deals from listings that are cheap because nobody wants them.
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?
Days-on-lot is the strongest leading indicator of competitive pricing in a local market. A listing that turns over faster than the local average is, in aggregate, priced more attractively to buyers — which usually correlates with being below the typical price-to-market range. Slower-than-average days-on-lot can be the opposite signal: priced for the seller's expectations, not the market's.
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.
