Picked up my (2018) RS3 yesterday as a replacement for my (lovely, and under rated) S3. It's in Mythos Black with most of the extras boxes ticked by the original owner.
WOW - you can read the figures, but when you press the loud pedal the difference is ******* marked! The sound is also something special, all I need to do is find a nice long tunnel now. I think that I'm going to enjoy this.
I'm sure that a little while into ownership, I'll have questions for long term owners, so hopefully the advice will be forthcoming.
