How we calculate these prices
We track 14 active listings for this vehicle across dealer sites nationwide, updated every day. Average and median are computed from real asking prices on live listings. We exclude the top and bottom 2% of prices to remove data errors, salvage titles, and monthly-payment figures posted as if they were sale prices. Prices reflect dealer asking prices — not final sale prices — and exclude taxes, fees, and incentives. Trim and mileage move the price more than any other factor; see the breakdowns above.
