Last year at this time I got caught in a sudden rainstorm while driving home in my GT40 and was pleasantly surprised by how little water made it's way into the cabin. At the recent Road America event I drove through showers one evening, again with no significant infiltration. Tonight the weather dude assured us that there was only a 10% chance of an isolated shower, so I fired up the GT40 and headed to our village's weekly cruise night. I had just positioned the car when the only black cloud in sight parked itself overhead and proceded to dump a 10 minute deluge. "No problem", I thought. "I'll just hop in the car and wait it out. It will only last a few minutes." I climbed into the car, pulled the door closed and spent the next 10 minutes watching water pour through every conceivable crack, crevice and orifice. There were steady pee streams coming from the entire window perimeter on both doors, the overhead door seals and what felt like a garden hose trained on my pants leg coming from the central naca duct location on the cowl. Thoroughly soaked, I sloshed the car back home and pulled it apart to dry out. Soooo....it seems P2123 is no more water-tight than the rest of the bunch.
