I was in the same boat as you,
a s2k is what i wanted originally and so i test drove one, I was luvin it BUT
i then saw a 350z for a similar price and thought that's a lot more of a car, so thought id just test drive one to see if i like it
and yessss!!
i've now owned my 350z a month and luv it.. feels much more of a beast with a roaring V6!
