Carrier/rack problems of the 2005 Mini Cooper S Convertible

I have had a new problem every week with this car. I took it to the car wash just to find out that the convertible top leaks on both sides, at the 1st bend. The water was dripping at a fast pace. I had the top checked out for any problems prior to purchasing at which I was told nothing appeared to be needed. The weather stripping and top had no cracks are sign of wear. Just another headache within a month of purchase.
