unfortunately water leaks are very deceiving when it comes to finding the SOURCE of the leak. Trial and error is your best bet. Get creative, like the bag under the top idea is a good start. In my case the gasket water leak has been a known problem with older Boxsters (the2.5)... My dealer achully "supposedly" resealed it for me (for 200 bucks mind you) and when it still leaked and I mentioned MAYBE trying to add another layer of sealant they said NO and wanted to replace the seal that runs along the frame of the door sill on the car for an additional 400 something bucks. Had I trusted their judgement and gone with it I'd be 400$ short and still leaking... Resealing my door gasket and bottom was step 1 of my trial and error plan. I was lucky enough it worked. Good luck with yer M3. I definitely noticed the boxster pulls VERY well at higher speeds. For a 2.5L engine that's quite impressive I must say.
