I know there are a million old posts comparing the SAS with coils. I'm trying not to rehash this. What I want to know is how the SAS interacts/compliments the AWD of the D models. This clearly is a completely different driving dynamic. I'm ordering an 85D on Saturday. Despite all of my polls on TMC, I'm still up in the air - pun intended - on the SAS. Looking for your thoughts on how the SAS interacts with the D models. Thanks.
