How this deal is rated

OAV compares this 2018 Mazda MX-5 Miata 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. A dealer that claims its listings can manage its profile and have buyer inquiries routed to it directly. A paying partner's own listings additionally carry an OAV Verified Partner label on the dealer contact block and a link to the dealer's own listing page. That is the complete list of what a relationship with OAV changes, and all of it concerns the dealer's identity on its own listings. 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.
