It occurs to me to make an additional comment. Not knowing "where" the squeaking is coming from, I would suggest a conditional "treatment". IF there are any plastic, vinyl, or rubber surfaces that might possibly be the source of this noise, use a bit of Shin Etsu grease to make it go away completely.
I had what I thought was a metallic squeaking in my S2000 hard top where it seals to the windshield. Turned out to just be the rubber creaking against the metal windshield frame. 'Dealer treated it to a little Shin Etsu, and it never came back (that was several years back). Good stuff if it's that kind of a problem.
