What this build asks today

Asking prices of live dealer listings decoded to this exact configuration — narrower than the trim-level figure, because every car counted here shares the same engine, transmission and drivetrain.

$91,348 median asking price · 8 listings · as of Aug 30, 2026

Too few listings to publish a price range — with 8 cars on the market, the cheapest and the dearest are single cars, not a spread. The median above is what they ask in the middle.

Where this data comes from

Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.

Prices are asking prices from 8 live dealer listings decoded to this build , last updated August 30, 2026 . They are what sellers ask, not what buyers paid.

Vehicle counts come from the 89 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
