About This 2026 Toyota Sienna

Listing updated: Sep 15, 2026

Listed by a franchise dealer in Vienna, VA · On lot for 9 days · VIN verifiable at NHTSA

This used 2026 Toyota Sienna Platinum is listed at $60,973 by koons in Vienna, VA 22182. It has 2,000 miles on the odometer (dealer-reported, not independently verified by OAV). It features a 4WD drivetrain with a 2.5L I4 engine and CVT transmission.

OAV's independent, evidence-backed Price-to-Market analysis rates this vehicle as Fair Price — priced in line with the supported comparable range. OAV has not assigned a reliable comparable market range for this vehicle yet — the available comparable evidence isn't sufficient for a reliable verdict.

This vehicle has been on the lot for 9 days.

Analysis powered by OAV's patented inventory standardization technology (U.S. Patent No. 12,236,477). Verdict methodology ptm-verdict-v1 · snapshot Sep 15, 2026. The patented comparable band is the input; ptm-verdict-v1 is the versioned OAV rule set that turns it into this verdict.

Market context

This listing is part of OAV's broader Vienna, VA minivans market analysis. OAV compares vehicles by local and regional price-to-market ranges and comparable count; days-on-lot and demand signals are shown separately, not as verdict inputs.

How this deal is rated

OAV compares this 2026 Toyota Sienna 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 a meaningful margin (OAV's minimum-gap rule); a listing below the floor by less than that margin is Fair Price.
  • Fair Price — priced within the expected range for comparable vehicles.
  • Overpriced — priced above the typical range for comparable vehicles.

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.

How this listing is verified

Vehicle attributes (year, make, model, trim, mileage, location) are standardized using OAV's patented methodology (U.S. Patent No. 12,236,477), which normalizes naming conventions and deduplicates cross-listed inventory across the dealership network. Listing data is processed daily; Price-to-Market analysis uses comparable vehicles.
