The MkIIIC was a long time in coming.  The original MkIII has been an outstanding customer chassis, its resume speaks for itself:  41 victories in 87 starts.  The beauty of that chassis was its simplicity, a steel tube frame with a push-rod V8 clothed in high downforce bodywork.  The MkIIIC continues on that theme, simplicity.
