Thinking about these two cars in Avant form. Previously had a B8 S4 and loved it. There's not much 0-60 between the B8 S4 and the B9 272, I do around 12k miles a year and it does far better MPG but I do love the B9 S4. Main concerns are around handling and braking systems. How much of a difference is there? Won't be getting one with Audi sport diff. Thanks in advance.
