Just for the record, the Audi unintended acceleration issue proved to be user error. Virtually all cases were new owners who simply stepped on the wrong pedal (I believe all the cases were owners of 3k miles or less). One of the big shots at Audi offered to sit in the driver's seat of any Audi with an unmodified brake system with HIS foot on the brake, then they could do whatever they wanted to the transmission. The claim was a transmission problem. His answer was the transmission was fine and even if not, the brakes do stop the car. This one pretty much rates up there with the faked pickup truck fuel tank fires and the comsumer reports rollover issue.
As to the Focus, I have not heard anything bad about it. It looks to be a small car for a specific purpose and market that performs as it should. Not a C class, but you knew that already. As always, YMMV.
