Is this 2026 Toyota Sienna Platinum a good deal?

OAV verdict: Great Deal

Why: Listed at $40,110, below a broader same-model range of $60,979–$65,833. That range spans trims and configurations and sits above this vehicle's MSRP, so OAV does not state a precise trim-level discount yet (52 comparable listings). Days on lot: 14 days (market average 24 days).

Manufacturer MSRPReference

$44,310

This vehicle $40,110 · $4,200 (9%) 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.
