Just in quick defense of the 951, if the one you drove was rattly (sp?), someone needs to tighten some screws. Mine has 113k, and except for a very slight rear hatch rattle over rough pavement, which can be fixed by re-gluing the glass to the hatch, it is as tight as a new car. It also has had most of the suspension re-done recently, so that probably helps in the tightness department. It's an excellent daily driver, but I have to admit, if I were in your shoes and already had a Porsche, I'd go for the S4. Extra space, at least as quick as the Carrera in a straight line, great creature comforts, and Quattro so you can leave the 911 in the garage when the weather sucks.

Also, Audi is bringing the new A3 to the U.S. Not sure about an S3, I haven't heard anything about that.
