Rain water in my car!!
 

So I took my new to me cooper (2013 Cooper S) out for a drive today when it started to pour rain. When I got to where I was going, the rain continued. When I went to leave, I opened the car door and TONS of water went from the roof straight into the car AARRGGHH!! How do I keep it out? It seems like a serious design flaw. Any advice from the experienced would be greatly appreciated.

Check The drain for the sunroof. My 2002 did the same thing.
