370z and odd noises.

Clutch out in neutral might have a little noise, might sound a little like a "bad" noise like metal-on-metal/bearings but some noise is normal. It's the throwout bearing.

You also might get a bit of a "clank" or "clunk" when you press the clutch down while rolling, that's also normal.

However, grinding into 2nd is not normal, and if the dealer is telling you that, then you should take it to another dealer.
