Dear people, in my Smart fortwo cabrio bj. 2009, water has been invading again and again for a long time. Under the flap in the trunk it is always full of water after a rain. Luckily it does not enter the engine compartment (not yet). However, then always fog my windows and it smells already modrig. The floor mat passenger looks not good any more. I looked under it, but it is so far dry. I have read to drill holes somewhere, only exactly where and if this is the solution, I wanted to ask here again. Do you have some helpful ideas. LG VinSander
