I had a 2011 S4 and sold it for the M3. I really like the M3 but I feel that for the money the S4 is a great package. I loved driving it on the Autocross event and it never had any lag or lack of pull regardless of the RPM's. My wife who also did the event said "the M3 is still a better car, but if we ever purchased another S4 it is still a great car". Hey, the "wife is always right, or is it a happy wife is a happy life!" I really wish I could have driven a TTRS however. If the TTS felt tame, the TTRS probably would have been solid.
