After a week of agonising over this very issue I have reached the following conclusions.
I nearly sold my 350z but.... If I was to have a weekend car it would have to be a roadster. They arent available yet. The one thing I HATE about the 370z roadster is that stupid aerial.
I sat down and had a think. Problem solved. I will be spending some more money on the 350z
Which is clean again btw.
