I really miss the auto lights and wipers that I had on my old 2.0Tq, which my S3 doesn't have! It looks as if I can get the package retro-fitted for about Â£500, plus the cost of a new windscreen. Has anyone else done this? How much does a new rain sensor-ready windscreen cost? (I don't have the heart to take a hammer to my current windscreen to get insurance to pay for a replacement!).
