Thanks everyone for the great suggestions and links, I'll be using them soon, I plan on checking the cowl this weekend in dry weather. I still have no idea where the rear water leak is coming from, luckily the front leak is very minor in comparison.

It's been raining these last few days, and the interior is staying dry, though the rain has been kinda light.

I wished I could park this car inside, but our garage has become essentially a man cave and motorcycle storage. We do have a couple of car ports, but my wife's car gets priority for one spot and my new truck gets the other. I would put a car cover on the Crossfire, but with it's 18 year old paint, I risk damaging the clear coat from water being trapped between the cover and paint. I found out about this issue last year, the paint was permanently damaged in a couple of spots because of it. So the car cover only goes on during the dry summer.
