 We ordered a 2009 R320 to replace our 2006 R350 coming off lease. The diesel is giving us exceptional fuel mileage, 24 city, 29 highway in the first 800 miles. The turbocharger fixes the woeful under torque in the R350. The steering is too numb, giving little feel of the road. The command system is a bit improved over the older system, but the screen is too small and the navigation presentation poor and behind the competition. The sunroof is nice and the interior build quility superb. Benz remains far behind the Japanese competition in features and price, but they do not have competing vehicles with the R. It is ridiculous that xenon headlights and push button starting are not standard.
