Abstract: An integrated parts location and transaction system for original equipment manufacturer (OEM), non-OEM as well as aftermarket automobile parts is adapted to be integrated with business management computer system (BMS) software, currently used by automobile dealerships (210) as well as repair shops. All participating parts suppliers, including dealerships (210), and repair shops are networked together, for example, over a combination of public and private communication networks to enable participating parts suppliers and potential buyers (for example, dealers and repair shops) to easily and quickly locate as well as buy and sell parts from each other.
