Nismo accessories ???

[Parrotguy]

I am planning on ordering a 370Z roadster soon, in pearl white, and was looking at the available accessories.
Nissan offers from the factory, painted, Nismo aero body part extensions for the front, nose, side rails, and rear quarter panels. You can order the parts individually. On the Nissan site click on the car, then accessories, then Nismo accessories. These parts are not very large and therefore don't seem to change the overall appearance of the car very much, at least as far as I can tell from the photos. The parts are not cheap either - prices are shown alongside.

I was wondering if anybody bought these, whether they seem to make a noticeable improvement in the cars look, and whether they are worth the money. They don't have any full car pictures to help you see the change. If anybody had some pics that would even be better.
