I`ve been checking as well and it seems so far that Mercedes-Benz has nailed it with the Quality-Factor for the W221 S-Class. For it`s 1st year in production, with so many electronic features (maby more than any other car on the road today), the King of the Crop excutive cruiser S-Class is doing mighty mighty well.

Believe me, I keep an eye on the quality factor in the 1st year and the new S is one of the very FEW cars` I would buy in the 1st year. It`s a winner and is as close to perfection as you could want in a european excutive luxury car.
