A novel and non-trivial system and method for restrictively exchanging and controlling vehicular data between communication devices of a private network is disclosed. A processor in communication with a plurality of user communication devices is used for controlling and restricting the exchange of vehicular data. In such network, the processor may establish a communication connection with an initiating communication device of an initiating user, receive initiating vehicular data from the initiating communication device and corresponding first users (e.g., defined trusted users) data, provide the initiating vehicular data to at least one available first user communication device, receive responding vehicular data responsive to the initiating vehicular data, and provide the responding vehicular data to the initiating communication device. Additionally, the processor may provide interested users who have not been defined as trusted users with the initiating product data and receive responding vehicular data from such interested users.
