i have no experience with ARS in the 6 series but in the 550 there was a night and day handling difference with and without the DDC/ARS. I felt the main difference maker was the ARS. I could not have seen myself purchasing an f10 without it. I didn't feel i needed it on the f06 as car already feels more stiff and handles better. As Bonz said, all f06 cars in the US come with DDC. ARS is a standalone option.
