Most convertibles will have water leaking in using high pressure car washes. Some may leak more than others. Some may never leak. Some may leak from day one or develop it later.
Our G35 coupe has doors with frame-less glass. The glass presses against a rubber seal in the frame and shifts slightly up under the roof-line when you close the door. The doors leak some water going through high pressure car washes but nothing that couldn't be handled. The car never leaked water driving in rain. I believe the manual even stated to stay away from high pressure car washes.
I don't think it's a BMW specific problem but a convertible specific problem. You bought a car without a proper roof. That being said, I have seen some videos with literal water falls inside the cabin in the hard top convertible. Yikes!
Oh, and I second DSX's (even though I mostly despise popcorn)
