MM’s S197 Test Mule, v1.0

This extremely-yellow Mustang was our first S197 R&D car. Acquired by MM in December of 2004, we tested it at Buttonwillow Raceway before its first oil change. While we used it primarily to develop our S197 parts, we installed a unique suspension as a design study for display at the 2005 SEMA show. We replaced the 2005 in early 2014 with Test Mule v2.0, a 2014 model. This 2005 still visits us occasionally. Its new owner is local, and uses it as his track-day car. He comes by when he needs new Hawk brake pads for the track. Photo by John Thawley III.
