Well...
I had a budget of around 40k and had aspired to own a RS for a long time. I thought that I might look at other options at the same time for fun. On the day, I drove the Alfa first and was really taken by it. I then drove the RS. The whole time I was in it I was grinning madly and having a blast. When i got home I started thinking about how I wanted to drive. The Alfa seemed more in line with how I felt including having a more classy feel. In some ways the RS seemed a little 'boy-racer' to me.
I am exploring it still, but the Alfa is plenty sporty for me and I am loving being in it. I surprised myself with the way I went too.
