E class reliability...
Edit: Also want to make sure - these cars are rear wheel drive, correct?
Avoid diesel engines, search using google and read this site thoroughly.
Avoid the M272 V6 engine used pre-2012.
Seek the V6 M276 engine from 2012 and later. Later models are more desirable due to early teething pains with chain tensioners.
V8 engines are generally reliable, there are some smaller problems experienced but less than the diesel and M272.
Avoid air suspension due to long term reliability and repair cost. Seek steel sprung vehicles of the latest model year and lowest mileage your budget allows.




Depends on your budget, seek a model with radars. They are high-maintenance items as well, especially when you live in high-corrosion area, but really add to confidence of driving.
Airmatic is another luxury, that comes with high maintenance tag, but reality is that if you seek low-maintenance car, go see Toyota.
Lot of choices, so good luck seeking.

For less issues, I would say you want to go later in the series: late MY '13, or for the more current look: MY '14. Our early build '13 required the timing chain tensioner update and had the oil in wire harness problem, both of which should be non-issues with late 13s and 14s.
There is a forum member that has a very nice E550 for sale down your way...
Best of luck in your decision making, but do go drive one of the E550s I mention - our decision was made as soon as we did...





I also have a W203 (C320). It's 215 hp, 3.2L engine was 55 hp more than a Nissan 300ZX (160 hp) I used to drive, a very competent sports touring coupe. So, the increase in horsepower in the C320 was a nice revelation.
Likewise, going from 215 hp in the W203 to 305 hp in my 2016 E350 is more than a welcome improvement. IMO, the E350 is more than "sporty" as well as luxurious. Others with racing experience seem to gravitate to more and more horsepower wherever they can find it, so I understand their attraction to the E550. But for me, the E350 has all the power I need, on the rare occassion when I "need" it.
Two years of ownership on this W212, without any reliability issues at all.
As for which model to shop, these cars depreciate like crazy the first 3-years from new. IMO, a MY 2016 will find its depreciation levelling off by now, enough to make the facelift model an economical find that will hold value for awhile. Being an end of production run year, the 2016s have some goodies thrown in that were options in years before. (The wooden sport steering wheel isn't even listed as an extra cost option on my car, for example.. And the final version of Comand NTG5/5.5 is more forward upgradable to Apple Carplay/Android Auto than the NTG4x versions prior to 2016.) So, these are some things to consider.

And let's not forget there are 2 levels of performance above the 550 in the E Sedans: the AMG E63 (which seem to be depreciating quickly) and its more popular brethren the E63 Model S - both a serious step above the 550 in all areas of performance, and they appear to enjoy good reliability as well. Just thought I'd throw that out there, since OP's net was cast wide...

I mention this, because my W203 did not develop its best fuel mileage until it had nearly 40,000 miles, a result (I think) from the religious use of Mobil 1 fully synthetic oil... i.e., I think the choice of oil delayed full break-in of the engine components til this milestone. Presuming the E350 is treated the same -- and it will be -- I think I can expect further fuel mileage improvement with the E350 (with just 26,000 at present).
I think this advancement can be attributed to the 7-speed (vs 5spd) auto transmission, and the extra torque of the E350, both useful in more efficient city driving. On the Interstates, I usually achieve up to 30mpg in the W203, while I regularly see 33-34mpg in the more powerful E350.

If you're planning to keep the W212 for the amount of time you've kept the W203, I would go for the NA M276 3.5L E350. I would skip any of the turbo engines - except the diesel. I would consider that but couldn't find one at a reasonable price with the options I wanted. I also don't care for driver assistance until it evolves more. I find the systems more annoying than helpful and keep my passive lane keep assist system switched off. Lots of people here will advise you to seek a car with the driver assistance package, but in my opinion - not necessary. They're hard to find and the system in the W212 is at least a generation old now.
My recommendation - buy a 2016 E350. It's well sorted, had updated COMAND NTG 5, and all of them have collision prevention assist plus with automatic emergency braking which is one driver assistance feature that all cars should have. Try not to get any of them with the burl walnut light wood.. that fades. Look for dark ash wood or open pore ash wood (which is what I have and love).
EDIT: not sure if this will be considered an unpopular opinion here, but do not buy a 4Matic. I see you live in the desert. Having test driven them, I found that RWD feels much better out on the road to drive every day. Also, they add complication and expense to maintenance. Just reading another active thread right now about how the oil pans on the 4Matics have axles running through them.

IMO, 4-wheel drive is best used in iffy driving conditions, like severe rain, snow, etc. But it's been my experience that when driving conditions are bad, I leave the Mercedes in the nice, warm garage, and take a 4WD something better suited... something that you don't mind sliding into a ditch with.

Also while the E550 is nice, the last year was 2014 and they command a decent premium over the E350. They're also not that easy to find as they didn't make that many of them. But as others said, 2016 is probably best if you can afford it. Apple carplay/Android Auto was only on the 2016, can't really retrofit it to the older models unless you switch out the comand completely and go with an Android/aftermarket system. Driver assistance package is one of the rarest to be found, but not far behind is the lighting package. You can tell from the front headlights. I'd probably suggest at least 2014+ as you have the face lift and a bunch of new tech like the collision prevention although you also end up with auto start/stop which people also hate. After the 2014 E550, there's also 2015/2016 E400. Not the same power as an E550 but still more than the E350 and those came with real leather as standard and those also tended to have more options. I myself would love to find a 2016 E350 with the driver assistance package, lighting package, parktronic, pano roof, keyless go and real leather usually the most I find them with are 3 or 4 of those options. If you find one with the Bang & Olufsen® Beosound™ Premium Sound System, that would be super rare as that was listed as a $5400 option.

I have only 1 comment for those "after spending all his savings on car, the guy had nothing left for advanced driving lessons. "
That said, my econobox diesel managed do skid on dry asphalt with some sand on it. I did practice lot of ice driving, but that was over 30 years ago, so I was glad to notice that trained reactions stay for years. Just like bicycle driving.

I truly appreciate the responses and insight.
I prefer rear wheel or all wheel drive to front wheel drive. I believe CLA went to FWD? Wanted to make sure E class variants hadn’t gone that way.
I live in a smaller town and 85% of the miles I’ll be putting on the car will be in town, so gas mileage is a factor but not a show stopper. No diesel for me. Definitely interested in Fallen’s E550. Window sticker claims 17mpg city(?) which is doable, I’m not sure about 12~14mpg… I’d also prefer a reliable normally aspirated power plant.
A coworker had a W211 E550 and got rid of it after having to replace all 4 corners of the airmatic suspension one at a time. He loved the performance and the way it drove.
I’m looking for something sporty in the sense of a sports sedan – which I guess is still a little vague. I’m coming from an ‘03 c230k, on which I had a tune done, put on H&R springs/sways with Bilstein sport struts/shocks, 4-piston calipers up front/2-piston calipers on the rear, etc.
DFWdude!!! I still have an extra one of your hood ornaments! I hear you on the fuel efficiency of the newer and more powerful engines. A few years ago I went from a 2002 ~250hp V8 truck to a 2009 ~350hp truck and get the same if not a little better gas mileage.
You E550 guys – what mpg’s are you getting in city only driving? And on the highway?
LILBENZ230!!! Yes – long time no see. Yep, plan is to keep this as long or longer than the 230.
Right now I’m leaning towards a 2016 E350. Looking to check one out tomorrow with the sport package and premium package. Still eyeing Fallen’s E550 too.
Any more insight or advise is appreciated!





Oddly enough, a 1972, 442's 300hp is essentially the same as the W212 E350. (Except the 442's 455ci engine barely yielded 8 mpg.) At least it was a 2-door, frameless window "coupe." Let's be honest... The E350 (or E550) is none of this, with its extra doors, framed windows, and automatic transmission. Neither is the BMW 5-Series for that matter.
However, trading up from your C230K's 189hp, any W212 will be an eye opening "sleeper" experience. I thoroughly enjoy mine.

Here is a snapshot of E350 mileage, on a 70-mile trip from urban St. Louis to a small town in mid-Illinois, 1st half city, 2nd half highway, 53 mpg avg.

Like you - I also had an M271 equipped C230K and the 302hp M276 in the E350 feels night/day difference. Much stronger. Also no real fuel efficiency penalty.
Note that most E350s have squared tire setups, but if you see one with the AMG split-spokes these are staggered. As far as the E350 being sporty, I would say that's subjective. It drives like a RWD car that feels smaller than it is. It is extremely competent. I wish the steering were heavier, though.
One last comment I'll reiterate, since you definitely have "sport" in your blood
For some folks "enough" is plenty, for others "more" is what scratches that "sport sedan" itch...





OP says he lives in a small town. After showing the handful of enthusiasts in a smal town what a beast the 550 is, there won't be many occasions to strut the stuff afterwards.
I'm more than happy with the puny, anemic 302 hp in the E350, instead, thanks.

And it sounds like he is leaning 350 anyway, so maybe it's all moot...
