The ones I've looked at on line are 2016 and 2017 - they are in a dealer local to me.
How harsh is the ride? I'm at an age where harsh isn't good. Daughter has an S-Line A1 and it does my head in with the bumps.
I'd skip the A4 s line unless you are mainly on motorways, went for a drive last night and I can feel every bump. To the point I've always been interested in switching for an A6 all road or similar with adaptive suspension.
What year of A4 Avant are you looking at I have a 16 plate 2L quattro I'm thinking of selling. It's on 83,000
In my 10,000 miles it's had
Ad blue tank replaced
AC pressure sensor
Brake pressure sensor
All front end bushings
I average 43 mpg locally but I'm always in sport/dynamic.
It's plenty quick, especially from a stand still.
Ride is harsh but it's on 19" wheels and has s line suspension.
