I've finally given up the unequal struggle with the S-Line Sports Comfort Seats, and sold the car to the dealer. Just made him about £3.5k richer, but you live and learn. A sad day On a brighter note, the dealer had just put his new S3 demo on display - by a spooky coincidence, it was Phantom Black with almost the exact spec I would have! It had the standard seats with electric lumbar support, and I only needed a brief sit in them to feel the massive improvement over the S-Line seats. Maybe it's a sign.....is there such a thing as fate?
