Nice one Oliver, my views entirely and I couldn't have put it better myself.
Yes, the super sport seats do look the business but are not that supportive and took me a while to get used to them.
The full width rear view camera image on the R is also a lot better than the squishy version on the RS, something that Audi seem reluctant to fix. Also on the RS the pre installed low resolution radio logos are rubbish and can't be manually loaded, plus the selected radio station cannot display music information on the same screen, where as the R can.
However, that super sound track of the sports exhaust at full chat leaves those little niggles behind.
I would also recommend the R, but if you are thinking of progressing then the RS3 FL will not disappoint.
