I've noticed a slight rattling on my 2011 Z. It seems to come and go, but it's exactly the same thing you mentioned here. The sound happens at low RPM's while going under 40mph and fades out after about 4k. After 40mph the sound seems to disappear altogether.

I had my dealership check it out within the first month I had the car but they found nothing wrong with it. 10k miles later, I've seen it come and go maybe 2 or 3 more times. It doesn't seem to effect any performance and I haven't found any distinct wear under the hood on anything.
