I have a 2010 v36 and I have done around 4k driving in it so far, both freeway and residential driving. I have not experienced anything like what people have described, well not yet. I have found at times the car sits on high revs longer than it should. I have a 370GT.
When I was looking at the v36 I discovered there was a vast difference between the 2009 and 2010 v36's interior and the materials used. That was the reason I went for 2010. I never noticed much of a difference between the ride/drive quality but then again it was only a quick test drive in the earlier models.
