I bought my 2015 E250 Sport with bluetec for a great price at $45,000(that is after registration). These are the sepcs of the car. Diesel inline 4 cylinder, 196 HP 369 ft-lbs. @ 1600 rpm 28/40 MPG combined 34. I know Edmunds has it listed at 27/38 but that is incorrect. I am in love with this car and I am happy I purchased it. It has more than enough power and I love the fact that it is a gas saver. These cars are very popular in Europe, because they are efficient. I am also a German American 6f 1 and I have plenty of room. The performance is also excellent, you must understand you are not buying a Porsche. I would recommend this model to anyone but I would get it pre owned because new these cars are over 60K.
E 250 Sport BlueTEC 4dr Sedan (2.1L 4cyl Turbodiesel 7A)
I have had several e classes and this is my third diesel; had a 98 E300 and an R320. There have been no unscheduled pit stops and it has remained tight, quiet, and returning terrific MPGs. On open road to San Diego, with V1 protection so high cruising speeds, I had 39.9 MPG. Overall mileage when averaging 30-40 mph over 12K miles, it is returning a steady 36.2 - 35.1. It is a great basic car, the right size for everything. I have had 2 S-Classes, and the size got me, a 2012 550CL which let me go way too fast way too easy and the long hood was a pain in a parking garage, always concerned I was going to see a wide-eyed pedestrian hoping on that hood as I leveled off. Note that it is a diesel and it takes a moment to spool up from a dead stop but has adequate go and I have never downshifted for any mountain driving, a nice feeling. But, above 70 you have to let the torque take care of passing tasks, at that speed and above there is not enough horsepower to downshift and put you back in the seat. I have 7K more miles on my lease and thing it may be time for a cabriolet!
