Prices are asking prices from 23 live dealer listings decoded to this build , last updated September 13, 2026 . They are what sellers ask, not what buyers paid.
Vehicle counts come from the 7,486 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
