In reference to the trunk leak ...... I have a silver 91 Miata and had SEVERE 
moisture inside the trunk lid. I was also told it was a condensation problem 
that couldn't be fixed by the dealer. Not true. One way to check your molding 
is to put white lithium grease around the molding and close the trunk. You 
will see contact of the molding by where the grease is left on the trunk lid.

    My problem had to do with the antenna. It had a non stock replacement. I 
replaced the mast and the base with factory Miata parts. (totaled about $25) 
It fixed the problem with not a drop of moisture! It didn't even appear to 
fit incorrectly until I replaced it with the stock one that is AIR TIGHT! 

Hope this helps someone!
