- “Ralf is the living spirit of German Motorkultur, the guy who understood what was going on before everyone else did and not only brought it into the public eye, but discovered he was part of it himself. He has the unique gift of being at the right place at the right time, just when something is starting to happen, and to look at it from a distance. Genius? Madness? I don't know, but the results are brilliant. I can't think of a person I'd more like to join on a high-speed, cruller-and-absinthe fueled-1,000-mile trail of mayhem across Europe. And so help me, one of these days I will." – 29. April 2009, David Traver Adolphus, Associate Editor, Hemmings Motor News
- “I have had the pleasure of working with Ralf for several years now on different projects in the European automotive sector. He is highly professional, creative and easy to work with. Our business relationship is very close and I am looking forward to working with him in the future.” – 26. November 2008, Dirk Behlau, Graphic Designer, Pixeleye Interactive
