PDX.... that is an old thread, and I haven't been in anything new today, but I would say, even though I am a short guy, the room is about the same. I liked the XF seats better as I felt the Z's were more competition seats, a little firm. I like the Z, but I wouldn't own one. I enjoy my XF's. I want a new Vette, but I am too close to retirement to have my mid-life crisis all over again...lol
