I have a 74 911 targa. With all the rainy weather in missouri the last month, my car has standing water inside, generally on the passenger side. There is no apparant water leaking from the targa top seals, at least when I'm driving the car. Any thoughts on where to look? Thanks, Dave

 

My guess is the targa seals are what is leaking. I would imagine the targa has drain holes in the body where the targa top mounts, so you might want to check and make sure those are not clogged.
