— Donlen Corp. has launched a set of cutting-edge Lifecycle Optimization Tools. In conjunction with these tools, Donlen established the National Auction Index (NAI), the industry’s largest database of vehicle resale transactions. The NAI is a collection of vehicle resale data, powered by AuctionNet, taken from wholesale auctions throughout the United States. With more then 6.5 million wholesale transactions reported annually, the NAI provides data necessary to support the series of analytical tools that enable users to completely understand cycling trends. As the cornerstone for the powerful tools, the NAI supplies the data used to perform vehicle trend analysis, generate instant Fair Market Values (FMV), and evaluate entire fleet portfolios in a few steps via FleetWeb, Donlen’s fully integrated online fleet management system.
