Greetings everyone,

There is a 2009 C250 CDI Estate in my possession at the moment. Even though it's in fine shape, I've been wanting an E Class for the additional room and comfort it offers for the past five years. With the kids, we go on many long vacations.


Up until now, I've been debating between an E350 CDI in AMG or sport trim (barring any compelling arguments to the contrary).

I am satisfied with something that has a few kilometres on it because my budget is only around £15k - £20k. I paid 70k for the C250, and now it's worth 160k. I'm not quite ready to leave with it just yet because, with the exception of routine maintenance and a few anticipated problems, it has been an excellent, trustworthy vehicle.

Seems like I need some guidance on which years are the most dependable in terms of the engine and other important mechanicals. And if there's anything in particular I need to keep an eye out for when I inspect the vehicle, please let me know.

In ahead, I'm grateful.

Your computer's findings, particularly regarding average mph over the five years, would be of great interest to me, as I own the same, albeit facelifted, S204 and don't often go on lengthy excursions.

Unfortunately, and I don't mean to be discouraging, people often have a string of bad luck after purchasing or upgrading a vehicle, particularly one that is no longer under warranty and has seen better days. You know where you stand when someone has owned a car, taken care of it, and done what was needed. But I know how you feel about wanting a change every once in a while; I had a C class for two years before upgrading to a gle a decade ago; I really like the extra space in my car. For three days in 2017, I was the proud owner of a Mercedes-Benz E-Class that I rented from MB. A mule

I drove more than 360 miles in a single day while getting my nox repaired. I'm not exaggerating when I say that it was far more pleasant and easy to control than my prior C-classes.
additionally to the present gle. Still, I thoroughly enjoy driving at high speeds.

May the force be with you

By the way, I purchased my C-classes in the early 2000s. They were the older, gasoline-powered models, not the newer, superior model (in my opinion).

Can you tell me which year and model you're looking for? Considering your budget, I suppose a W213 is in order. However, it will be the E350d, not the CDI, and the AMG-Line, not the Sport. The older W212 models, like the one I own (a W212 E350 CDI Sport), are the ones that use the CDI and Sport designations. You can find even more recent models for less money than you think. All 350 213 dervs and later W212s will feature AdBlue, but I'd rather hammer nails through my foreskin than purchase any MB diesel with it.

And I agree with the 'Adblue' person on this front. Especially if you prefer shorter excursions, as I sometimes do.
I didn't know about the AdBlue difficulties a decade ago, and the gle is my first diesel vehicle. But if I were, I still probably would have bought the gle instead of the AMG because that one is too noisy and expensive to repair. He maintained it for ten years with low miles, but the parts/labor plus the fact that he hardly used it caused him to sell it and downgrade to a petrol C class. His sister had the AMG CLS, which he had purchased new about 2010 (maybe a year before or later).


When I say "too loud," it's because I used to work for a London municipality and frequently visited people's homes after I got the gle in 2016.
and in some regions where I conducted evaluations, it would have been asking for trouble to have my car vandalised.
At around 5 or 6 weeks old, the GLE AMG Line was keyed; I never had it fixed. Then, a vandal ding was placed in right below the passenger side door handle; I never had that dented either; it irritated me.


The thought of vandals shouldn't deter you, but you should give some serious consideration to the garbage AdBlue.

I've seen a lot of vlogs with Ford Transits, so it's not just MB cars and adblue.

Much obliged for your emails.

That information is completely foreign to me. The monthly mileage is about 40mpg, based on what I see on the screen. I have a heavy right foot from all the short journeys I take escorting the kids after school and on weekends, on top of the lengthier trips I do for business every day.

This is something that has always bothered me whenever I've purchased a new car. This one follows two sS204s and a W202 that came before it. I was patient in my search for one that appeared to have received excellent care. The fact that it has been so dependable makes me reluctant to change it. However, the expected trend of general maintenance expenses rising with age is evident.

Thanks for the clarification. I'm still a bit confused about the proper names and could need some help figuring them out. I was perusing the S212 and S213. Can you elaborate on the problems with AdBlue? I'm not familiar with them. The diesels' power delivery is better, in my opinion. Although I was considering S212s before, I must say that the S213's more contemporary interior is much more appealing. It feels like a significant upgrade. Should I be focusing on a specific year or years? My goal is dependability, as I mentioned before.

In my opinion, you should look for one that isn't Adblue, preferably from an earlier model. However, I don't think you'd be able to find one that is within your budget if you did (the year is dependent on the engine; allegedly, one or two got Adblue in 2011). With their low peak revs and plenty of low-down torque, the later turbo petrols are like dervishes to drive. Given your financial constraints, my recommendation would be one of those. There is a lot less room for error, but unfortunately, your budget does not cover the E43, therefore it will likely only have four cylinders.
My original intention was not to get a derv, but after researching the 350 CDI, I came to appreciate its silky smoothness, abundant torque (540 nm at low revs), and respectable gas mileage, qualities that were lacking in the feckless 4-pot petrol engines of that era. Back then, the AMG E63 just wouldn't cut it as a daily car. It was wonderful to find one that had a Sport pack instead of black leather. It wasn't until after I purchased it that I learned it was a unique W212 E350 that was ULEZ compatible despite being built to Euro 5 requirements. What a bonus! Usually dervises are required to be Euro 6 spec for that. Even though I rarely take the car to London, having it on hand during sales is always helpful.

Blueffiency S/W212 is devoid of Adblue.Since I own one, I am aware.
Adblue is offered by BlueTec in S/W212.

The following may or may not apply to S/W212 vehicles manufactured before or after the facelift; I'd be pleased to be corrected if you disagree.

Review the data displayed on the dashboard; I have recorded an average speed of just 22 miles per hour over the past twenty-five thousand miles.

Wow, I usually reset it once a month or right before a major vacation.
