While we make every effort to ensure the data listed here is correct, there may be instances where some of the options or vehicle features may be listed incorrectly as we get data from multiple data sources. PLEASE MAKE SURE to confirm the details of this vehicle with the dealer to ensure its accuracy. Dealer cannot be held liable for data that is listed incorrectly. MPG estimates on this website are EPA estimates; your actual mileage may vary. For used vehicles, MPG estimates are EPA estimates for the vehicle when it was new. The EPA periodically modifies its MPG calculation methodology; all MPG estimates are based on the methodology in effect when the vehicles were new (please see the ?Fuel Economy? portion of the EPA?s website for details, including a MPG recalculation tool).
The Manufacturer's Suggested Retail Price excludes tax, title, license, dealer fees and optional equipment. Dealer sets final price.
