Abstract: A method of providing a periodic vehicle order count recommendation for supplementing an inventory of a motor vehicle dealership to satisfy periodic market demand. The method includes the steps of converting a sales history database and an inventory database for the dealership into a dealership data structure, and obtaining from an agent of the dealership, query parameters including a specified sales history period, a forecast period, and a market region specification. The method also includes the steps of accessing a database of VIN numbers registered with a government agency, decoding VIN numbers registered within the market region, and storing resultant registered vehicle information into a regional vehicle registrations data structure.
