Gotta be the itch in most cases. Sure as hell was for me. Evaluating the options left me with just one, and I am so glad I waited. Have to agree with Rich slightly, in that I wasnt getting a smile on my face with the Zed, except for places like Wales where you could really drive it. The new Zed is not as much a brute, but damn good fun for hacking about, and the smile is back. I think its mostly down to getting used to the power you have and not fully exploiting it as much, getting complaicant with it. Since getting the new Zed, I've had more spirited drives and the love is definately back
