Abstract: An embodiment provides a data processing system comprising a processor coupled to a memory for storing a machine learning current value model trained to output a prediction of current value, the machine learning current value model representing a set of vehicle features and historical secondary market transaction values. The processor is configured to create a set of inventory records. The processor is further configured to extract a set of vehicle attributes for a respective vehicle from an inventory record, create a feature vector for the respective vehicle based on the set of vehicle attributes extracted from the inventory record, determine a current value for the respective vehicle by processing the feature vector for the respective vehicle using the machine learning current value model and update the inventory record for the respective vehicle by adding the current value for the respective vehicle to the inventory record for the respective vehicle.
