Abstract: Sales data and vehicle data may be collected by a vehicle data system embodying a special sales analyzer application. For each dealer affiliated or registered with the system and each vehicle transaction record received from the dealer, the system may run analytics to determine, compute, and/or impute supplemental data and internal vehicle pricing data such as trim-level vehicle configuration data, price ranges, exclusion reasons, dealer-specific recommendations, etc. that can later be used to generate a dealer-facing custom user interface. The results are collated into a comprehensive database and persisted in a data store. When requested by a dealer, the system may retrieve dealer-specific information, including sales prices, salespeople, average dealer margins, sales volumes, etc., and anonymized sales data from others in the same geographic region as the dealer and display a visual presentation of all transactions and also individual transactions for that dealer.
