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.
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.
I purchased a 2011 E350 Bluetec with 80k miles. I did some research before purchasing and liked how the Diesel engines seem to take on lots of miles with out too many issues. I knew, however, that there were some issues and made a budget on how much I wanted to spend for the car and how much I expected to pay in the potential issues. That was probably the best thing I did. The Diesel engine for this year had two main issues that I came across in my initial search. The rear main main seal leaks as well as the seals or gasket on the oil cooler. Unfortunately for me, those were the first two things I had to replace... it was not unexpected but it would have been nice to have left the money in my bank account. The parts were relatively inexpensive but the labor cost was... well let's just say the mechanic I took it to was more than happy to do the work. I ended up spending about $2800 but that is far less than what it would have cost had I taken it to the MB dealership. That issue aside, the car is solid and drives extremely well. It's not a sports car but it is as fast as I need it to be. I drive primarily on the highway so 0 to 60 is not very important. I currently am averaging about 34 mpg. If highway traffic is light, I can get as much as 38 to 39 mpg. Heavy stop and go highway traffic and I am getting about 25 to 27 mpg. My work commute is over an hour so the time I leave from home or work does affect my mpg. Road noise is almost non existent... if traffic is light, I set the cruise control on 75 mph and just zone out to the road ahead. The day Mercedes sells an autonomous driving car will be the day I fall a sleep in the back seat. My wife drives a 2006 Lexus GX470 and it's not as quiet as the Mercedes. That being said, The interior is comfortable but it's not as comfortable as the Lexus GX470. I test drove the 2012 version of this car with the "real" leather seats and I could swear that the seats feel different (i.e. more comfortable) but I chose this one with the "fake" leather because of the price. The layout of the interior is good. My only issue is that the air condition controls feel too low in where it was positioned (a personal preference) and the cruise control seems out of place. I initially thought I would not like the position of the gear shift but after a while it did not bother me at all; I also thought that the knob in the center console would be annoying to use for the phone, radio, navigation but to the contrary I like it more than a touch screen. I really like this car and have been quite satisfied with almost all of it's features. It is not my first luxury car to own (it's my 4th) but is the first Mercedes I have owned. I will add, though, that maintenance is expensive. In fact, unless you can afford a good trustworthy mechanic, I would recommend you become a weekend technician. This means doing your own fluid changes (particularly the oil), minor engine repair and maintenance. My father is a retired Diesel mechanic so there is some advantage for me in owning this car but there are some things I just do not have the time for. Like the repairs I mentioned earlier. I left the car at the shop for 3 days on those two repairs. Funny thing is, I know how to do the job but I am not a certified technician that does stuff like that on a daily basis. If i can't do it myself over a weekend, then I have to go my mechanic... or I should say, my dad's friend who runs his own repair shop.
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.
I have owned this MB E350 for almost 3 years and bought it privately with 84,000 miles and it now has close to 150,000. This one had all the bells and whistles on it from the first owner. I am the third owner. Massaging driver seat, sports package with Distronic Plus cruise control, panoramic sunroof, etc. For the long trips this car is the one to have as it practically drives itself. Smooth ride and quiet inside, in spite of it being a diesel. Some reviews by the pros say it is slow off the gate, but I have not found that to be the case for it being a sedan. Miles per gallon on a recent trip was 36 MPG on over 400 miles and with a 21+ gallon tank, your range is exceptional. I have been able to hit a high of 40 MPG on almost all highway miles and don't ever recall having my lowest below 23 MPG. If you own this vehicle you will need to have a good foreign mechanic, who may end up being your best friend, as you will spend a good amount of time with him/her and probably help support their 401K and children's educations. I still love this car and plan on keeping this car and am religious about servicing it on schedule, but have tracked its overall costs over the years and have had what I believe are general wear issues such as replacing engine mounts, alternator and belt pulleys, brakes and nox sensors. The real bug even the Dealer has not been able to handle is the constant check engine light, relating to the EGR valve. This is a real pain if you want to have a clear cluster on your instrumentation, but now I have just come to live with it. The Dealership actually stopped returning my calls, so I am assuming this is something MB does not care to deal with and I have seen no recalls related to it. Remember: Parts and Labor can be a huge gouge out of your bank account when owning one of these cars, but they are a pleasure to drive!
