Who Owns Who, the leading source of franchised dealer information, is a comprehensive directory which lists more than 300 retail groups each with three or more site locations – covering a total of around 5,000 outlets.

Each group is listed alphabetically by the name and address of the ultimate parent company complete with phone and fax numbers and website addresses where available.
