Aston Martin values are available online at KBB.com and NADAGuides.com, as of 2015. The websites provide prices for Aston Martins of various years, models and styles. The prices range from high to low based on the car's condition.
Kelley Blue Book offers pricing for new Aston Martins and breaks down the cost using anticipated local taxes, fees, down payments and total finance amount. It also specializes in pricing used Aston Martins. Users select the trim, style and accessory options, and the website delivers a price range based on the user's location.
NADA Guides offers a similar website structure, but it uses a third-party website, AutoTrader Classics, to find values of older Aston Martins.
