Bought a 2014 e350 convertible with 11,000 miles on it. It was a MB certified pre-owned car. Fun to drive; problem was the drivers side window would not fully close. After four trips to the dealership in 4 weeks, the window would not still not consistently close. Hard to own a car you can't drive in the rain. The dealership was great - they tried the specified MB repair four times but it would not hold. The dealership took the car back with no hassle. MB was not good (: I spent $1,500 on prepaid maintenance that they would not return. Didn't matter that the car could not be used as a regular driver. You should be ashamed MB. My next convertible will be another BMW.
This is my first Mercedes. Have owned BMW740 ( perhaps worst car I have ever owned) Infinity Q45, and Lexus LS 430. This car is as fun to drive as any of them . As far as ride quality goes, however, the Lexus is leaps and bounds in front of this car. However, I got this car for the performance and it has not let me down. This car jumps when your doing 40 and step on it. It is flat out fun to drive. My older Corvettes were to old to compare but insofar as fun factor, yea its right there. Seats are a little stiff, sound system is okay, nothing great. The nav system is so-so at best, seems like most in cars are years behind the cell phones anyway, but it does work.
Do like being able to sync my phone and not have all the info stored in the car, in case the car is borrowed for a long period of time by people I don't know. Without a doubt the best part of this car is the performance, gas mileage is actually not to bad considering and at times on the freeway I get over 25 mpg.
Without a doubt it needs heads up display and blind spot indicators on the side mirrors. Such an easy feature these days considering all the cameras around the car.
I love the look of the car, the more aggressive grille that comes with the 550 and the performance is exquisite. The 402 horsepower and 443 lb/ft of torque usually puts me at 60 in about 4.6 seconds. The car has a great ride quality and when in sport mode really feels like a 'Drivers car." When Driving the car there is a noticeable rattle the comes from the A pillar and is present even on fairly smooth roads. Convertibles are more prone to these types of issues however when driving a BMW 650i convertible this rattling was not present. Furthermore, there is a slight squeaking noise that seems to originate from the front axle or suspension and just occurs now and again and then goes away.
Performance, Engine sound, Multiple Sport Modes which tighten the suspension, sharpen steering and improves engine response and acceleration. The look of the car is already great but with the 550 comes a more aggressive front and back bumper, and slightly flared out rear wheel wells. The breaks are also wickedly strong in this car and in my own testing appeared to bring the car from 60-0 at 100% breaking in between 106-109 feet.
4matic, Hard top roof and slightly more head room in the rear seats would make this car even better. Also, even in Manual transmission mode l the car will shift for you well before the red line. When in manual, the shifting should really be completely in the drivers control and if the car does shift for you, this should only happen if the engine is in danger of severe damage due to driving past the red line for a prolonged period of time. Lastly I believe that the car should probably be sold for a little less than what it goes for. My car is priced at $82,000 and I could have gotten a BMW M4 convertible for around this price range which many may believe would be "more bang for your buck."
I leased this car after a few great years with an E-Class Sedan. It was basically perfect and I had a lot of trepidation about switching to a less practical car. I love my new cabriolet! It's got great steering and handling, a wonderful turn radius and the trim level is terrific. Otherwise, I love putting the top down on any dry day.
Awesome speaker system, slightly better navigation system than previous years - you can say the whole address at once and the Bluetooth is more responsive. AirScarf is great - also enjoy how smooth conversations are with windows up and Aircap on the highway.
Here are my small gripes: I like the old dual headlights better than the single one - I find them a bit cold. Also, the cupholders aren't well placed - with things in them, you can't really get to the AC controls easily. Obviously, I wish this came as a 4Matic and would love better gas mileage, but knew what it was when I signed up for it. Also, the iPhone interface doesn't jibe well with iOS 7 - at all. This was a problem on my 2012 E350 Sedan as well.
