Whether you are looking to trade in your car or simply sell it you'll need to know about how much it is worth. These third party tools can help give you an idea of how much value your vehicle has. Use of this questionnaire and the resulting trade-in value is a dealer-provided estimate for information purposes only. Your vehicle's final trade-in value is set by the dealer after inspection and is based on vehicle condition, mileage, vehicle history and repairs, your location, and other factors. Your estimate value does not factor in any remaining balance you may have on a current lien.
