I am loving my S3, as you said it is everything you need in a car and so much more.
The S-Tronic box is just so good, it's so easy to use and the shifts are so quick. My S3 has the Adaptive Suspension, which I think is standard on the Cabriolet, is great. It makes the car so much more usable. I previously had a standard Mini Cooper and its ride was so much hard than the S3 in Comfort Mode.
It just but a smile on my face everytime I use it. It is such a lovely place to be.
I bet you can't wait for the new car, what colour are you thinking of?
