Even though I don't have a 370z, thought I'd just pop on here to report a sighting: white Nismo 370z in the Bellevue area. Saw it twice during the same day - last Saturday in the morning near the Bellevue Fred Meyer's and a 2nd time at 7:30pm'ish in or around downtown Bellevue.
Whenever I pass one it makes me sad and regret choosing an A4 over the 370, but hey, at least I've got practicality, huh?
