Well, the last few days I've been noticing a "tap tap  --- tap" noise
from somewhere within the Coupe.  I know the rear louvers are functional
(in the same way as described above for the 5k), but never connected
that with my recent noise.  I'd open the window to try to hear it.  It
actually sounds like outside trim wind-slapping against the body.  With
the window open, it won't happen.

Betcha' when I check, it's the flaps in the rear louvers.  Wonder what's
changed recently, 'cause it didn't happen before last week
