Update on the car
All dried out after 2 days in the garage, constant air blowing through the a/c system and one really really hot afternoon in the sun (I think I scorched my bum for this one). Also found the answer to the problem on the internet! Ain't google something? Apparently, for those sun roof and moon roof owners, there are drainage channels from the slot corners. The front drains into the front doors, the rear drains behind the rear bumper. These channels get clogged on a periodic basis and need to be cleared. After some tweaking and getting goo-ey black stuff on my hands, water ran clear out the drains. Hooray! It poured this morning too and the car was dry. Am much pleased.
