Disappointed in this cars suspension qualities over rough roads.

But on the plus side you have a significantly better engine than the anemic 268HP E350. Plus you don't have to sit on plastic seats, or suffer during night driving without the bi-xenon lights on the P1 E350 versions.

I do agree that comfort mode on airmatic is not a 180 compared to the sport mode and do wish for a greater difference between the settings but the roads in L.A. are decent most of the time, potholes get fixed fairly quickly and freeways are pretty smooth. That's we pay higher gas prices.
I am actually a big fan of the suspension. Great for a family sedan. Comfortable, accommodating, and ok road feel. Perfect for the family car. It would suck on a race car, but it's not a race car.
As I stated in another post, I doubt anyone wants to be able to tell if the coin they just ran over is a dime or a quarter. Most everyone wants some degree of isolation from rough patches of pavement and imperfect roads.
Road "feel" means different things to different people. IMO, a perfect car is very communicative and provides feedback from the tires, suspension and steering wheel. Especially at the limits of the car. At the same time I don't want a jarring ride over rough pavement.
And I do agree with you that the E350 and E550 can be jarring over rough pavement. However, I disagree with your comment that a BMW is like a "gocart". Test drive an F10 and let me know what you think.
The Best of Mercedes & AMG

I drove my sister-in-law's E350 coupe and felt that it drove and handled great, quick and firm, much better than the sedan.
My 80 year old mother always said her caddies had excellent handling. However, her definition of good handling meant that the power steering had enough boost so that she could easily maneuver the barge-like car around the parking lot at church.
Message is that everyone defines good handling differently. I define good handling in that the car does exactly what the driver requests and provides communication and feedback. A car shoud respond in a linear fashion to inputs, and should be neutral and predictable in it's behavior when it exceeds it's traction limits.
You can have good handling at low speeds but it becomes increasingly more difficult at higher speeds - as you approach the limits of traction -and will understeer or oversteer.
It is not difficult to exceed the limits of traction especially around tight corners at higher speeds or accident avoidance.
I think a lot of folks confuse handling with how smooth the car feels - especially over rough roads. My response to this is always that the suspension should idealy be as soft as possible, and only as stiff as necessary.

I might be satisfied simply because I didn't have any special expectations because "this is a Mercedes, it should be near perfection." I really don't think of it as a true luxury car, and I certainly don't think of it as a true sport sedan, regarless of V6 or V8 configuration, due to the sum total of all characteristics and attributes. I do, however, think of this as a good overall sedan, much in the tradition of E's that preceeded it. I can't remember ever looking at any of the pre-212 E iterations and thinking of them as the plush of luxury or the performance of sport (except in AMG form), but always thought of them as cars of substance built for the long-haul, and that was what I was looking for, and feel I got, when I purchased mine.
Interesting to hear about the E550! Wow. I gotta say, the extra power or cylinders doesn't mean nearly as much to me as the perceived added comfort over harsh roads, and it's sad to see that doesn't exist!
I think Avantgarde and Elegance in Europe compare to the Sport and Luxury in the US.
The E still shared first place with the new Audi A6 though, both ahead of the F10.

My understanding -- I've discussed this with several race car drivers and a NA BMW exec -- is that street cars are typically and purposely set up to favor understeer rather than neutrality. This is because the typical driver's response to "being in trouble" is to lift off of the gas and jam on the brakes. This is (done correctly) the correct response for understeer. It is the wrong response in an oversteer situation because the weight transfer "pins" the front wheels, making the car rotate around them -- that is, it makes oversteer worse.
A tendency to understeer or oversteer is not necessarily a sign of bad handling. In Formula 1, my understanding is that some drivers (e.g., Jenson Button) prefer the car to understeer. Other drivers (I think, e.g., Michael Shumacher) prefer oversteer. I am personally much happier with oversteer.
One job of the suspension is to absorb impacts from rough roads, so it doesn't rattle your spine, or put pressure on the cars structural integrity.
The W212 has what has been awarded, and what is known to be possibly the strongest and best/most advanced structure in automobile history.
When I go over rough roads, my suspension CHECKS OUT, and ALL the pressure goes into testing that phenomenal structural integrity. It's like I can hear my cars structure loosening and weakening up every time it trembles because the suspension is too incompetent over rough patches. This makes me curious/concerned as to how well the structure of these cars will hold up to their 100% ability, once the miles keep racking up.
I find the handling to be excellent considering I wanted a Sedan with a stately and Luxurious/weighty feel. However, if any of you care THAT much about handling, you bough the wrong car, and your money was ill spent. Drive an Audi A7 and your E will feel like getting into a floaty Truck, while the Audi will feel like a go-cart (and it's a bigger car to boot). I loved getting back into my E after getting out of the Audi, but that's because I want my car to ride like a solid Sedan, and the driving position and interior ambiance felt so much more calming and open/luxurious, however, I was upset in the fact that although it rides smoother on solid roads, it rode even more roughly on rough roads, and didn't have the handling benefits to boot.
Then let us vanity freaks have what-would-be the more rare and putting-up-with-roughness of the Sport Package.

I want to make this clear, I am ABSOLUTELY IN LOVE with my car. It's kind of sick really. I want to keep it 'till the wheels fall off, that's how much I love it. I'm just I guess being hard on the one aspect that is bothering me. Aside from that, this car is a dream, truly.
It's funny, because I went to go check out the new Dodge Charger (not to buy, or replace my E with of course, maybe to replace my Chevy with in a year or two), which my Muscle-Car side was hoping would be a truer testament to the original, and I keep hearing about the improved interior.
Well, I saw it, and it was nice.... kinda, and the interior was.... uh.... nice, for a Dodge? It actually felt like hell in there, and I almost wanted to vomit. Walking over to my E, immediately the sculpted and immaculate sheet-metal lines told me that it "isn't that Dodge", and the interior confirmed to me that it is absolutely worth the price of two Chargers, lol.
