Don't know M3 specific but my E21 320i (almost an M3 right? ;) and my E30 325i seem to work the same... *so*

It certainly could be the drain holes being plugged.. I had water leaking in my 320i until I used a long wire and then some compressed air to blow the holes clear.. roof never leaked again.

Same symptoms - rained over night.. got in car.. noticed a drip on ceiling.. drove a little bit and got a nice trickle of water on my head.

Again, after clearing the drain holes (front and rear) I never had the problem again. They were really gummed up before cleaning out.

hope this helps
