welcum, get a 5 speed, when i was looking for my z i first test drove a auto and it seemed very slugish ( the n/a) but then again i didn't really go hard in it. and besides the 5 speed in a Z is like one of the best 5 speeds you will ever drive and in the Z it is not hard at all most ppl that have driven my car (family) said that my car is the easiest 5 speed that they have ever drove.
