I can find the secret compartment but can't find what is causing a rattle that sounds like two pices of tin rubbing and rattling together. Could it be the :
1 wind screen assembly?
2 hinges on the glove box/ secret compartment
3 soft top assembly
4 Lucid rear speaker assembly
5 two coins lost in the convertible well?
Let me know if you have had this problem and what it was while I still have my hair and wits.
Thanks,

 

I'm getting a vibration noise in the glovebox door. I've gotta fix that, but for you, I'd check the tie down for the spare in the trunk. That can sound like it's coming from the cabin, but it's just that the bolt is loose.

 

Try the spare tire hold down. It sounds like you describe. Just try tightening it a few more turns.

 

I know it was lose after the 1st auto x of the year and after the last time I cranked it down. I will check it at lunch. Thanks for the tip.

 

It was the spare tire hold down hardware. This is 2nd time it has losened up after getting cranked down after an auto-x. Thanks for the help.

 

I also noticed a rattling coming from around the "secret compartment" and on my car it was simply the wind screen needed to be moved about a centimeter becuase it was rattling after opening and closing the compartment it moved a little and was making contact with the roll bar/headrest or the compartment. But, either way, just try adjusting the wind screen either a little forward or a little backward and see if that fixes it.

 

Holy crap! I think that was it! Its been driving me NUTZ since I bought it. My spare nut tightened 2 complete turns further.
You guys are geniuses. You really are. Lets hope I don't hear that buzz anymore...

 

That wasn't it. I tried lining the secret compartment with sticky compression foam. Seems to be better.

 

Nope, that wasn't it either. This is ridiculous.
