New GS owner, some basic questions...

Hello,

I picked up a new GS a couple of days ago on my way to buy what would have been my 6th Porsche.

Loving it (of course) but relatively ignorant about this car, and particularly the F1 tranny - great but need some time to get used to the concept.

Some basic questions:

* Exactly when would the CC decide to shift into Neutral? I know it happened to me a couple of times during the test drive, salesman said it was something like 10 seconds after being off the brake pedal, but lots going on at the time and I don't remember the details.

But it's got me somewhat paranoid driving in traffic, can it shift into Neutral, for example, when crawling at a couple of mph without gas or brake pedal input during bumper to bumper traffic, or slowly advancing to position for a left turn at a big intersection?

Or is it only after getting off the brakes after a full stop?

* In regular city driving I hear a non-engine sound, appears to be from the passenger rear area, which is like something rapidly spooling up or down according the car speed. Not a bad noise, just curious as to what it could be.

* Haven't had to put gas in yet but the setup seems exrtemely prone to gas drops dripping into the bodywork when removing the nozzle - any tips on this?

* Hearing conflicting opinions on the need to break in a Ferrari engine, comments?

Thanks in advance!
