Guys, better compare the F30 interior/IDrive vs the S4 interior /MMI. Then the F30 will win. Just because it's newer(better integrated)
Coming from a F10 5 series I cannot see why the Audi A6 interior/MMI should be better and/or more ergonomical. I think they are on par. I prefer the F10 5 series interior by far over ANY Audi interior....
