We've had this car for 7 months now, and it is our all time favorite vehicle. Elegantly designed and mechanically superb, we have driven it with pleasure and in comfort on snowy roads and in Washington's steam-bath summer. The fuel mileage is not great (about 19 mpg), but that seems to be an inevitable tradeoff for cars of this class.
Beautiful styling, interior and exterior. Excellent handling on the road, with the signature Mercedes tight turning radius. We have a 10-year old C220, and most of its flaws have been ironed out in this 2005 model.
Like its C-class predecessors, this one has a very thick center post area that makes rear/side viewing less than great.
