thanks very much for that. it was exceptionally enlightening and helpful. i did not realize that the 350Z (apparently) does not have the depth and/or robustness that the TT has. that will definitely play a huge role in my decision. i have only owned Z's since i was 16 (along with a few other vehicles) so, at 41, i'm very much a veteran. i do genuinely appreciate the solid race-car feel of my TT.
