Difference in 2017 and 2018 E43
If there was an RMS leak issue for M276, we would had saw it mentioned numerous times on the W212, W204, W205 forum, the M276 is one of the most reliable MB engines and it has been around for a long time in both naturally aspirated and turbo charged form, especially the former.
Edit: The only main issue is the startup rattle (camshaft adjuster) which is pretty much resolved in the later years of M276. Otherwise, the M276 is a tried and true engine. Dare I say it is the most reliable part of the entire car.

With all the problems that eventually causing RMS degrade prematurely, I understand what you mean. Seems the owner didn't take care of the car well, irregular or extended oil change.
The mechanic told me it will take about USD400, incl part and labour to replace the seal. I thought where I stay, tropical country, average 33'C whole year, seals accelerating degrading is normal. I had changed them in my Alfa Busso V6 before as well.
Sigh.... trying to sum up my feeling now

What else would they be hiding? Unless this is really the only car in the market, I would think twice before getting it.
Especially if overfilling engine oil could have the potential of engine damage as well, those are hidden damages you can't see until you take it apart.

1. His ownership is about a year and I found the advert posted last year. He actually inherited this paint himself. (Previous owner's fault but still a fault I know)
2. When I did the inspection last week, they checked the engine oil level was normal.
3. There is one other car in the market but was red, sprayed black and I don't fancy chestnut brown seats.
Today, he went to his workshop and they offered a year's extended warranty (for a 6 yrs old car), covering engine, gearbox, transmission, drive shaft etc. Prior to that they have to perform their own inspection before offering their warranty at a premium. They did their checks and found out only the valve cover leaking, no sign of leaks from transmission and rear main seal. Valve cover resilicone will cost me $300.
After all was cleared, they proceed to change engine oil and ATF fluid. Bummer part is... They used 5W30!
I believe car can still be driven but I will change in a shorter interval, perhaps after 3K miles with no spirited drive. 1. His ownership is about a year and I found the advert posted last year. He actually inherited this paint himself. (Previous owner's fault but still a fault I know)

Just to share with my new friends here that I finally got my E43, yes it's the 2018 version and about 60K km old. Car is black and shiny

So far what I have done in the last week before I collect my car over the weekend was to change engine oil, transmission fluid, differential oil, steel brake hose, spark plugs, etc. Car is going smooth and enjoying my ride. Thanks for the advice again all.
Very thorough service too, nice!
I'm also glad you didn't go for that mango car that was a mess.

Enjoy!!!
Everything done with original parts and I found out Benz has some queer standards and I haven't had time to find out alternative non MB brands. For example, Dot4.2 brake fluid. I went "duh?!" Haha!
