My answer is no, sadly. After buying the Z, I soon didn't fit in it. I had grown a couple of inches, and gained some weight.
So now, the Z is gone, and I'm in a G37. So far, I like it much better. Less harsh, more classy, pratically the same power and tranny, striking looks: everything I wanted from the Z.
