Agree with this, my first year of M4 ownership was depressing until I sorted all the rattles. One major issue I found in the RS3 was the seating position. I'm 6'1 and my head was almost touching the roof at lowest in the super sport seats. I just felt I was looking out the top of the windscreen. I don't have that with the M4. Worth the test drive of the RS3 if you fancy one, was a great car just not for me.
