Manufacturer MSRPReference
$73,855This vehicle $69,121 · $4,734 (6%) below MSRP
MSRP is the manufacturer's suggested retail price, shown for reference only. OAV rates new-car deals by how far below the LOCAL COMPARABLE MARKET a vehicle is priced (see OAV's market comparables / MRP and sold-price value / TRV) — not by discount from MSRP, because dealer-supplied MSRP is not independently verified. The advertised price is set by the dealer and may require financing, rebates, trade-in, or other qualifications, and excludes taxes, fees, and dealer add-ons — confirm the out-the-door price with the dealer.
