Jasper Valley Motors (JVM) is a family-run auto dealership selling both new and used vehicles. In an average month, JVM sells a total of 160 vehicles. New vehicles represent 60 percent of sales, and used vehicles represent 40 percent of sales. Max has recently taken over the business from his father. His father always emphasized the importance of carefully managing the dealership's inventory. Inventory financing was a significant expense for JVM. Max's father consequently taught him to keep inventory turns as high as possible.
