How this deal is rated

OAV compares this 2018 Nissan Titan XD against similar vehicles currently available for sale — same make, model, and year range, using trim where the data supports it. OAV does not adjust comparable prices for mileage; on used vehicles it withholds a verdict when mileage would distort the comparison — very high or unreliable mileage, or a lower price better explained by higher-than-typical mileage than by a genuine market discount — rather than overstate a deal. Based on where this listing falls in that comparable set, it is rated:

• Great Deal — priced below the comparable-range floor by at least OAV's minimum-gap margin; a smaller gap under the floor is Fair Price.
• Fair Price — priced within the comparable range, or below the floor by less than that margin.
• Overpriced — priced above the comparable range.
• Unscored — OAV withholds a verdict when the evidence cannot support one: too few or too widely spread comparables, a price it cannot validate, a branded or salvage title, or mileage that would distort the comparison. The listing stays visible; only the rating is withheld.

Listings show OAV's Price-to-Market verdict and live market context for every dealer's inventory, whether or not the dealer has any relationship with OAV. Shopper questions reach dealers through OAV whether or not they have claimed their listings. A dealer that claims its listings can choose where those questions are delivered and read them in its OAV inbox; claiming changes nothing shown on any OAV page. A dealer that has received a shopper question through OAV has a green contact card; other dealers' cards are white. The color is not a rating, a verification, or an endorsement. While OAV tests the color, half of these dealers' listings, chosen at random by vehicle, show the white card instead. A dealer that pays for OAV Dealer Plus has an "OAV Dealer Plus" label on the dealer contact block of its own listings. The label means the dealer pays OAV; it is not a rating, a verification, or an endorsement. That is the complete list of what a relationship with OAV changes. Payment never changes a vehicle's verdict, its eligibility to be scored or cited, the evidence shown or withheld, or where and how prominently the listing appears on any OAV page, board, or answer. There is no paid placement, ranking, ordering, verdict badge, or featured position of any kind. OAV sells dealers insight into the evidence, never influence over it.
