Donald Farr has been a Mustang owner since 1970 and involved in the Mustang hobby as a journalist and editor since 1977. His first assignments were for the Shelby American Automobile Club and for a new magazine, Mustang Monthly. In 1980, Farr joined Mustang Monthly to become the first full-time editor. During his 18-years at Dobbs Publications, Farr authored Mustang Boss 302: Ford's Trans-Am Ponycar and co-wrote How to Restore Your Mustang and The Mustang Recognition Guide. Farr later edited Musclecar Review and Super Ford magazines before moving into the Editorial Director position at Dobbs. When Dobbs was purchased by Petersen Publishing in 1998, Farr became editor of Mustang & Fords magazine before returning to Mustang Monthly from 2003 to 2014.
In May 2014, Farr joined Pate Media Group as the editor of Mustang Times, the official publication of the Mustang Club of America.
In 1987, Farr wrote a Mustang Monthly editorial about Ford's plans to convert the Mustang to front-wheel drive and asked readers to write Ford in protest. Thousands of letters flooded Ford World Headquarters, which contributed to Ford's changing its plans. The front-wheel drive platform became the Probe and the revamped 1994 Mustang continued with rear-wheel-drive.
In 2010, Ford Motor Company asked Farr to revise his original Boss 302 book with new chapters about the 2012 Boss 302. The updated book, Mustang Boss 302: From Racing Legend to Modern Muscle Car, was published by Motorbooks in July 2011. Two revised editions have also been published; one that updated the book to include the 2013 Boss 302 followed by Boss Mustang: 50 Years that added chapters covering the Boss 429.
For the Mustang's 50th anniversary in 2014, Motorbooks asked Farr to write Ford's official Mustang 50th anniversary publication, Mustang: Fifty Years, which was later updated into an overall history book, Ford Mustang: America's Original Pony Car. In 2015, Farr teamed up with Motorbooks and light-painting photographer Tom Loeser to produce Art of the Mustang.
Farr's latest book is the Ford-licensed Mustang: 60 Years, a compilation of significant and interesting Mustang stories from the past six decades.
Farr received a Lifetime Appreciation Award from Ford's Team Mustang in 2011 and the Lee Iacocca Award in 2012. He has been inducted into the Mustang Club of America's Mustang Hall of Fame and the Mustang Owners' Museum Hall of Fame.
Farr owns the 1966 Mustang GT hardtop that his grandfather purchased new in 1966.
