The Black Book Digital app is a remarketing tool that offers a quick, efficient way to search for vehicles and valuation data, including offering VIN scanner technology. The app offers information layers in additional modules such as Carfax, AutoCheck, trends, vehicles specifications, photos, and a Demand Index. The Demand Index functions like a heat map, allowing users to identify valuation trends based on geo-targeted activity and sales. The app downloads critical information, so users can access it offline if a Wi-Fi network isn't available. Users can also search Black Book Digital's Q-List, which helps automotive professionals manage inventory and share information.
