The January 2009 Street Rodder magazine has an article about the '33 Ford street rod that Factory Five is developing. In the story there's a brief history of the company and how they started out with their Cobra replicar; it says,
"Banking on their new car's performance, the brothers' car found immediate success among both street enthusiasts and racers who competed in various vintage and replica sports car events. Inspired by Tim Suddard's comment in Grassroots Motorsports magazine that the car would make a great vintage-style spec racer, the brothers established the Factory Five Challenge Series, a group of regional points-driven events where the company's customers could pit their cars against one another in legitimate race action on legendary racetracks."
I think it's kind of neat that they would do this - how often do you see one magazine even acknowledge the existence of another one, and yet GRM manages to get mentioned all over the place.
