I find the s line suspension settles down on the motorway. When cruising at motorway speeds, you wouldn't know it has firm suspension. (And you can construe 'motorway speeds' in whatever way you wish!)
Not so good. Had a colleague at work who's just changed his car (not Audi) as he suffered from a sore back on trips longer than an hour. Think it was more the angle of the seat rather than the suspension, but the point is it's worth changing if you're not happy.
Anyway - does next car have to be new? Check out A4 Avant Allroad (B8.5). Very comfortable ride and plenty low mileage examples out there fully loaded with extras. Good luck.
I'm actually taking one last punt and having an independent opinion from well respected Local Audi specialist. He's going to take a longer test drive and a longer look underneath. He will also price up a change to comfort setup.
I don't mind second hand but you simply don't save any money on finance until they are 3 or 4 years old these days.
I really wish I had picked the all road or at least comfort/ adaptive.
It's annoying cos my timing was perfect as I got 17 plate and missed the tax and price rises and also got 8.5k off
This just kills it though no matter how much I try to ignore it
