Tossing in my 2 cents on my first post. Part of the sports car experience are looks, road noise and ride. Either can be increased or decreased in comfort/tolerance depending on what you buy and what you drive it for. My new and first Z as of Saturday
(pics will follow soon) is definately a sports car and feels like it but it can be very civilized if asked to. The 370 has no bad angles to look at it from as far as I'm concerned and I've owned my share of sports cars. Even if I do have a non-spoilered roadster
.
Absolutely get a sport package, the syncro-rev feature is great.
A nav system, with all the great tech the jammed into it, is a definate must if you like connectivity to your phone/MP3 player/tablet. The 272 page manual takes some wading through though.
Build quality I cannot answer to, but there are more plastic bits where I would have rather seen aluminium or carbon fiber, but that too can be solved.
Fast, yes it is that, it will get you in trouble with folks who drive Crown Vics etc quickly but thats half the fun isn't it...
Lastly, at least where I live, there are fewer Zs on the road than many other sports cars, no being like everyone else is good.
Hope this helps...
