Took delivery of my 2012 MB E350 Sport "Launch Car" a little over a week ago. I must say this is my first Mercedes and I am very impressed with fit and finish and the upgraded engine. I test drove the new Audi A6, Lexus GS and the Infinity offerings. None of those cars had the warm classic feel of the MB. Even the new A6, while it is fast, the interior felt too busy and esoteric all at the same time.
This is my mercedes car No 5. Leased on 2-27-12. Ondrive home from dealership open hood signal was on It took some effort by 3 people to shut hood. next week A/C was not working, took it to dealership they fixed it. Some leaky valve I was told. on 3-21-12 dead battery.Car was towed to dealership on 3-22-12 new battery installed. Car is still at dealership we are trying to work with them. Road side service is overloaded with calls asking to call back unless it is an emergency. Looks like Lots of lemons on road. One review on cars.com is very alarming.
Having previously leased Lexus GS and BMW 5 series cars, this was my first Mercedes. It is a sporty luxury car rather than a luxury sport car. It drives very good (although not as tight as other sportier cars, it still handles nicely). The cabin is beautiful. The control system is about the same as other similar cars, and does take getting used to. I haven't had problems on the car, and drive daily in city driving. Very happy with this car.
This isn't a BMW Ultimate driving machine. Once you get past that and recognize that the M-B and BMW have different missions, each can be judged on its own merits. I was once a BMW guy. 3 series, 5 series, all great drivers cars. The 5, an E39, was also a supremely comfortable car as well. But all that was a while ago, and I just want to be really comfortable, and in a car that handles well (I'm not going to track the car). Given that portfolio, the E350 does quite well. The engine is smooth and powerful. The transmission is very smooth and the steering, while not the most tactile (uh, neither is a 5 series' anymore), is competent. The car is quiet and rides well. Lots of controls which could be daunting but I figured everything out by 2nd day I had the car. Surprisingly, I get better highway MPG than I do on my other car, a 2009 Honda Accord V6. navi has not sent me he wrong way yet, Bluetooth works well, and music register is a hoot. Back seat is very roomy. Gauges are clear and easy to read. MB-Tex is a convincing simulation. Audio system is good. Cons? Seat bolster are fairly aggressive- but that's been my experience with 4 other German cars I've previously owned. Controls are generally firmer than on a Honda- but that's just a matter of getting used to things. As is the location of he cruise control stalk vs. the turn signal stalk. Looking forward to 100,000 more miles.
I traded a 2008 E350 Sport for a 2012 E350 Sport primarily to get the more fuel efficient engine and an updated Command System. The Command System is a huge improvement; but I have been somewhat disappointed in the fuel efficiency. The EPA projected a 25% improvement (16/24 vs 20/30), but I have seen just a 10% improvement. Mind you, 19/29 in normal driving is not to be laughed at, but not what I expected. On a 1700 mile road trip which included several hundred miles of mountain driving, I did average 31.7 mpg. I would say that this car is more comfortable than the 2008. This is my fourth E Class and they just keep getting better. I have now owned this car for 3 years and logged 32,000 miles. It is without a doubt the best car I have ever owned. Normally after 3 years I would be looking for another car, but no matter what I drive, it just doesn't measure up to this car. I have maintained it "by the book", and the only surprise I have had is that I had to replace the motor mounts at 50,000 miles and this was covered by my CPO warranty. My favorite "creature features" are Keyless-Go and Bluetooth phone and audio. On my morning commute, I have to merge into heavy high speed traffic. This car has plenty of smooth power. I should change the title of this review to THE BEST.
