 I've been a Mercedes owner for 10 years now, and loved my cars. I started with a C class and then three E classes after that. I just picked the 2017 E300. I've never been so disappointed...First, let me say that I'm a very experienced technology consultant. The COMMAND system is way too techie. Many features take multiple actions, sometimes 6+ if everything goes right, and it frequently doesn't because of the swipe action. This makes it incredibly distracting to the driver, I hate to say it, but I feel unsafe changing the song in my car while driving.There are way too many inconsistencies in the rest of the electronics to spell them all out, but I highly encourage any potential buyer to take the car for a minimum of a couple of hours and really test it out, especially the COMMAND system.A few small things to note. There is no CD player. The engine is a turbo charged 2.0, I was told 3.0. Voice control is fair at best, I'd call it poor myself. On three separate occasions, the COMMAND system went blank, froze, and was completely blank. The dashboard clock continued to work and the COMMAND clock stayed at the same time.Remote features via MB mbrace, a whole slew of problems, again, too many to list.The dealership told me that it's not uncommon to have some problems with a new car, but I strongly disagree. I bought a Mercedes Benz. There is an expectation that I have as a customer that they are providing a superior product, in this case, my expectations were not meet; not even close. I've never any problems with my other cars, not even close to this.Last, but not least, my check engine light came on with less than 100 miles on the car.I would say buyer beware for sure, and trust me, I hate to have to say that.
