How this deal is rated

OAV compares this 2018 Porsche 911 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 typical range for comparable vehicles.
• 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 PTM-derived deal quality and live market context. OAV-claimed dealers manage their listing profile and route buyer inquiries directly. Paid OAV partners can surface additional verification signals, but commercial participation never changes a listing's Price-to-Market verdict, eligibility, ranking, or confidence.
