I couldn't let the Ferrari skin for the DGIV go unanswered, so here is my interpretation of a Vodofone McLaren XR-1! I could make a DGIV version of it if anyone wants one.
I rushed the first job on the McLaren XR-1, so I offer version 1.1 which is a little more subtle on the McLaren red (which is a wicked colour!), and the swoosh accent instead of some of the coloured panels. I'll work on the DGIV next.
