 This vehicle replaces our 2008 E320 Blue-Tec and what an improvement. Mercedes has made great improvements in cabin design and layout, improved the voice command control and greatly improved the navigation and radio manual controls. To top it off we're getting 38 to 40 mpg for combined city/highway driving (much better than EPA estimates and better than our 2008) and there's more than enough power to pass anything on the highway. This is a really great vehicle.
