making the switch to a Z, but have a concern

You didn't indicate in your post if you've driven a 370Z yet. I would make that your first priority. When my Z32TT died, I wasn't completely sold on going with a 370Z until after I drove 5 or 6 used ones. Full disclosure: I ended up buying a new '12 but I was very close to picking up a used '11 when the new one with all the features I wanted popped up.

Good luck with the search.
