Abstract: A vehicle data system having improved performance is described. In particular, embodiments provide system and methods for vehicle data systems that can both accurately predict marketing trends and presenting those accurate marketing trend predictions in real-time over a computer network. These capabilities, among others, may be accomplished by embodiments of vehicle data systems disclosed herein through the use of a bifurcated architecture by which a significant amount of detailed processing is accomplished in a back-end process, including the gathering and binning of data and the use of such data to determine parameters for models or adjustment components that may be used to accurately forecast market trends for new and used vehicles. In a front-end process, requests for such market trend forecasts for specified vehicles or locations may be received over a network.
