This is my second E-320. Both are fine cars, but the 2005 is clearly the superior machine. I think the best one-word description for this car is "precision". It is fun to drive and does exactly what I expect. In the first six months of ownership there have been no problems at all. Having suffered quality issues in recent years, Mercedes has returned to the high standards of old with a car which seems nearly bulletproof.
This car is such finely integrated equipment, both functionally and aesthetically, that it is difficult to isolate its attributes. I wish everyone had one of these.
