I have one of the first 2012 CVT Jazz's, it was registered at the end of May 2011.
I've had it since the end of November 2012 and I love it, even though the original need for it has now gone, I find it such a useful vehicle that I can't really find a reason to change it!
As some one has stated it's turning 2250 rpm at 70mph, which is part of the reason I chose the CVT.
