I also just bought an SR and organised for the dealer to fit a Webasto 'Hollandia 700' fully integrated sunroof. It was cheaper for the dealership to get it done than for me to take the car to the Webasto centre in Sydney. Which is the same place the dealership take them to, plus I won't be without a car while it is fitted. Cost $2000 through dealership, while I was quoted $2500 to have it done myself. I can only assume, the dealership gets a volume discount as they are a very large group. My car is due next week will let you know how it goes.
