Purchase advice S 500 M278 vs S 560 M176
I'm searching for a W/V222 with V8 engine. First I wanted to buy a S 560, but the longer I'm reading about this model type I fear that I could have much more problems with it than with the S 500 M278 pre facelift model.
I want to drive the car at least 10-15 years.
One weak spot of the S 560 is the R744 ac, that all S 560's in Germany have. The S 500 has the old R134a ac. In Germany are more and more people, that have problems with the R744 ac.
The other possible problems come from the engine M176. It is too overenginereed and repairs seems very complicated, as I saw in this video:
For me, the benefits of the S 560 are the nicer look, better headlights (multibeam) and the better comand/infotainment with integrated android auto and better resolution. But I'm not sure if this is wort it considering the possible issues of the engine and the ac.
What are your thoughts?




But it seems that it's very difficult to repair it or to change parts. In older Mercedes engines it was not difficult to replace a thermostat or the engine mounts.
For me it looks like that everything is difficult to replace on this engine. In the past I repaired or changed many things on the engine by myself, but I'm not sure if this will be possible with a M176.




People say that the MB warranty is the best, but this costs about 1200$/year and also doesn't cover everything. So I'm not sure about it to spend 12k over 10 years and in some cases I still have to pay additionally.
Maybe it's better to save money and go to another shop than MB.

I really don't think there is a reliability issue with the M176, its physically smaller than the M278 also which if anything makes it easier to work on, its also a hot V with the turbo right in the center.
If you want the same guy to freak you out about the M278 who freaked you out about the M176, here's his video on that:

Now brakes on the S Class were way more, at his shop I was just over $2,000 for rotors and pads and labor, where on the Lexus that was like $850.
But honestly, with a good independent mechanic this is not any more expensive to maintain really...
As of March 16th 2015,
Engine number start : 2789xx 30 266191, Mercedes change over to cast iron cylinder barrels. Along with new pistons and rings of course to match.”
As for the leaky cam solenoids/magnets, those also had updated parts addressing the issue, can’t seem to people on these forums with the newer engines having the issues and the cheap pigtails are an easy and cheap insurance.
For anyone who maintains their car, you can maintain a Mercedes for way cheaper than any Japanese brand. How? FCP Euro. If you have an Indy who will just provide labor, you can still have cheaper maintenance. I’ve had full sets of brakes replaced and countless oil filters, spark plugs, air filters, cabin air filters, all under the lifetime warranty at the cost of shipping back parts. Even oil, but I rather fork the money for two jugs at Walmart than the hassle of returning used oil.

330K miles would meet my definition of long term reliable.

Why are you saying the iron liners are urban legend? Are you saying that the were never implemented in the M278'S
