Is this still happening!
Our Cabrio was one of the first on the road in the UK. Early July last year and almost immediately we found we had to slam the boot lid to get it to latch, also the doors seemed to loose their alignment but still shut OK. Back to the dealers within the first week for the adjustments to be made and fortunately no re occurrence. Hope you guys over there have the new roofs, we had a bit of a saga getting a complete new redesigned roof fitted but glad its done now! She'll be a year old in a couple of weeks but still looks brand new!
