 This is my first Audi/German car. I was looking for a fun, safe, classy car that would accommodate my 6 year old twins. I looked at all cars under 60k. The S4 fulfilled all my expectations and more. I still find new features on the car, i.e. the way it channels rain over the car not on the side windows and the memory of seat, mirror and climate settings tied to the remote. The build quality is excellent. It is so solid. The speed is addictive.  Cornering is phenomenal. It's limits cannot be safely explored on the street.  I am a quattro convert.
