Wonderful car for the intended purpose; very happy with the purchase.
A most relaxing ride; very comfortable & supportive seats and least amount of road noise I have experienced in a car. Have the premium 2 and sports package. Got 46mpg with cruise control going 71mph on a road trip; around town average ~30. Get well over 500 miles per tank of diesel. Stereo system overall is fantastic, navigation system is a much needed improvement over previous generation and is very good.
Engineering is what is expected; best in class trunk size when trunk closes engineered to not pinch the luggage! All season floor mats a must for us; cost extra but are great.
Bluetooth works fine & easy to set up.
Blocks out most exterior noise.
AC, stereo system with i-phone are outstanding.
Spouse likes the driver side message and playing Pandora from the i-phone.
For several weeks in the spring diesel was cheaper than gas.
Filling up for fuel about half as often from previous car as the tank is large (~21 gallon) and gets great mileage.
Auto up and down for every window from all seats.
At ~ 15k miles, not a single problem with the car.
Purchased the trunk liner - feels cheap compared to Honda products.
Spouse wants passenger seat message just like the one the in driver's seat.
A little soft in steering/driving but to some extent was a known compromise driving a bigger sedan.
Keyless go works great but need to periodically replace batteries in FOB (~ 6-9 months & is easy to do).
Took too long to set up garage door opener from rear view mirror - finally called Mercedes and had it done within an hour.
Need to keep an eye out for diesel stations and only use the reputable ones.
Last but not least, this car is probably most expensive in class to purchase.
I have had this car since 5-2011 and have now put 15,000 miles on it. It's solid, fits me like a glove, handles well, if not like a sports car and has all the bells and whistles I need. I added the luxury package, steering wheel, dynamic seating (a must have) and the P2 package. Fuel mileage has been almost 32 overall and 36-39 HWY. The DEF fluid is no big deal. Buy at most gas stations or car parts stores for $12 for 2.5gals. I think I have added 5 gals total (maybe 7.5). Big deal. M-B will scalp you if they put it in but it's simply filling a tank. Love the car and not one issue.
Dynamic seating, comfort, torque, styling. I don't know exactly what it is with the styling but as soon as I saw this car I knew I wanted one. I'm not sure why but the package just seems to work. It's sexy, stodgy, cool...
Bigger wheels. The 17in wheels look 1 or 2 inches too small.
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.
Diesel power and fuel economy, its way better than EPA estimates. Improvements in radio and navigation control, real rotary buttons that work, and driver's side seat.
Provide same seating options available for the drivers seat to the passenger's side of the car an bring back the trunk closure button.
