I looked at various 4wd cars before I bought the S4, and NONE compare for the money. Most of my mates are into the jap stuff for all out speed and cornering like the car's on rails, depends what you're into. An old sparring partber of mine had a stripped out Evo 7 and it was blisteringly quick, but the MPG was that shocking he was scared to drive it, and remove it from its garage for the fear of twoc'ers.
An Audi is a thinking man's performance car, and are very comfortable, especially for those who spent years training martial arts, and taking beatings for breakfast.
S3 will be like going from an old pair of slippers to a pair of stillettos, good but not as comfy.
*Evo's do look and sound the ******, and deserve a straight through pipe for flame throwing and popping*
