How we calculate these prices
We track 9 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.
