A vehicle information collection system is disclosed for receiving vehicle information by way of a communication network and storing the vehicle information. The vehicle information collection system comprises: a vehicle information collection device for collecting the vehicle information of a plurality of vehicles from each vehicle by way of the communication network; and a point-issuing device that is connected to the vehicle information collection device by way of the communication network for conferring points to the vehicles according to the vehicle information. The vehicle information management unit collects and stores vehicle information at any time, and when a prescribed condition has been met, transmits vehicle information that has been stored and information indicating its own vehicle to the vehicle information collection device by way of the on-board communication unit and the network. The vehicle information collection device, upon receiving vehicle information from a vehicle, both classifies and stores the received information and transmits the information that indicates the vehicle and the vehicle information that has been received from the vehicle to a point-issuing device by way of the network. The point-issuing device, upon receiving these items of information, issues points in a number that corresponds to the amount and/or the category and/or the value of vehicle information and transmits to the vehicle information that indicates the number of issued points.
