I've heard this jingle noise from over too my head since I got the red head in March this year. I finally got the time to replace the sagging headliner yesterday and found the culprit.... This little gem was hanging from a stamped hole above the drivers door. The headliner had never been out of the car, how did the original owner not go insane for the first 100K miles? I assume it's a factory assembly fixture of some kind.
