The 2014 E250 Bluetec 4matic has a vibration at higher speeds that sometimes goes away once the car finds the right gear. I have 700 miles and the computer on the dash says I am getting 34.5mpg. The car gets over 40 mpg on the highway easily. I bought the2014 E250 Bluetec for the fuel efficiency, the longevity, and it is the only E class they had that still has the 3 point star on the hood. I have read all the horror stories about Mercedes Benz but at 700 miles I have not had a single problem. I think I will keep this one for a long time.

If you can, order the active multi contour driver's seat. It makes driving a real pleasure. The 40 plus mpg highway adds to the experience. Diesels are making quite a resurgence in the states, and for good reason. The suspension on the Luxury truly provides a much smoother ride than the Sport model. I highly recommend it and, at a minimum, try to drive both before you buy. It is becoming more difficult to find this type of "your father's" luxury car ride. Look no farther than this automobile. Buy one and enjoy the ride! Update as of 4/15/2016 -- Since I penned my original review, my statement regarding a resurgence of diesel cars in the states has taken a turn for the worse, given Volkswagen's troubles with testing. As recently as this week, Mercedes has come under scrutiny for exactly the same testing problems which falsely yield better mpg and emissions than reality might suggest. I will be pretty furious with Mercedes Benz if they were involved with this controversy. I purchased my car with the environment in mind and will feel deceived if they mishandled this ethical issue. Update as of 4/14/2017 -- Not much more to add. There is a second battery in the back of the car that is responsible for certain functions ( my favorite of which is the auto stop where you tap the brakes a second time and they stay on without your foot being on the pedal....great for long stop lights and hills), in any case that battery failed and was replaced under warranty. The ride is still very smooth and people still comment on how much they love the looks of the car!! Update as of 10/19/2017 -- Although the ride of the car still remains quite good, there is an option for air suspension costing around $2000 on the newer models about which Edmunds has written positive remarks. If I were to buy a new E class, I would add that feature.
Bought my E 350 new in July 2014. The car stickered at $61,250. Went to trade it in on another MB product in September 2015 and the dealership would only give me $37,500! Car was in perfect condition with only 8,000 miles. I would call this terrible depreciation. If you buy a new MB plan on keeping it for a LONG time.
I test drove one of these and wasn't very impressed. The engine under load sounds like an overstressed rental car. If you don't need the space, the BMW 3-series diesel is a much better car for less money. Or take a look at the A6 TDI.
Just picked up a loaded, ordered spec 2014 E250. Selected this primarily for the Distronic Plus with Steering Assist, diesel range and AWD. Cost not a particular concern. M-B USA definitely miss the point here for all their 'marketing prowess' - international versions have smarter equipment choices. As everyone notes: no power folding mirrors!? Forget the rest of the gizmos, not being able to fold in mirrors easily in NYC in a luxury is incredible. Tiny nav screen, no available rear heated seats, old fashioned Apple 32-pin connector on s new 2014 model).. c'mon how much are the bean-counters at M-B USA really saving here? Not a good first impression compared to my BMW Porsche or Range Rover.
