Black Book’s Used Vehicle Retention Index for March declined slightly.

The Index fell to 113.8 from 114.5 in February. The Index is higher than in March 2018, when it read 112.

The Black Book Used Vehicle Retention Index is calculated using Black Book’s published Wholesale Average value on two- to six-year-old used vehicles, as percent of original typically equipped MSRP. It is weighted based on registration volume and adjusted for seasonality, vehicle age, mileage, and condition.

Black Book announced new enhancements to its dealer-focused subscription application, Black Book Cherry.

Available via desktop or mobile, Black Book Cherry helps personalize dealers’ inventory process by automatically identifying the most desirable vehicles at auction, along with offering valuation and appraisal functions.

Replacing Black Book’s legacy mobile app, Black Book Cherry allows dealers to view all vehicles at an auction, VIN Scan, and free form search. Black Book’s History Adjusted Valuations are a standard feature in Black Book Cherry.

A Retail Market Insights feature was recently added to Black Book Cherry, This new feature offers metrics such as days-to-turn, market days’ supply, and average listing price. Users can also view individual listings to help gauge profitability and understand what is for sale in their local retail market.

Additional functionality allows users to “like” a vehicle, label it as a “cherry,” “dislike” a vehicle, or “share” a vehicle with a colleague or customer. Users are notified of new vehicles entering the marketplace.

Black Book’s Used Vehicle Retention Index fell to 115.4 in January from116.3 in December.
