Reliability/longevity of S550 vs E300





As for reliability, I'm not really sure you can make the case that the S550 is more reliable. The more tech in them like airmatic, the less reliable the car and the S class has a lot more than the E class. But if you get a CPO car, just get the extra 2 year warranty from one of the vendors mentioned in the extended warranty subforum. If the car has some of the original factory warranty left, you could end up with a car that has a warranty for 4-5 years.
If you go with the S550:
You know that 'emergency find' Dave Ramsey talks about. Better make one for your S550 as well, atleast 5K for catastrophic failure of suspension, steering and non wearable. I dropped 2.1k on a horn module and and battery replacement for non functioning aux systems...
But in reality 2.1k is 1.5% of the original MSRP. Picture is parts quote only...
OEM Brake rotors cost $300 each...
Almost everything is proportional to the original MSRP.
If you are an enthusist and are prepared go for it! The joy of owning a majestic S Class far exceeds and monetary desire or need of mine and I'll gladly pay for it's upkeep.
Depreciation having another perspective for me, good thing you are looking at used, might as well flush your money down the drain if you buy it new.

I also have access to the W222 table an it shows "N/A" next to almost 95% of the ratings for all 2015, 2016, 2017, 2018 W222 cars Then there is this message below:
"NA indicates that we did not receive a large enough sample size to provide data for a specific year."

Remember the reliability and cost of ownership service are not the same. Reliable means does the car go from A-B and back to A? Service cost is how much is the oil change? How much to replace pads/rotors. Quality is how it is made (Materials and things you feel and touch). I personally do not think a car is unreliable if the cars radio broke or the window gets stuck closed.

same here, in addition to the S-class, I also own Lexus LS. I bought my Lexus LS with 110Kmiles on it at that time, and today I have over 240K miles on it. No one believes me when I say this, but I swear that I never took the Lexus LS to a mechanic except for an oil change (and only once for brake+rotors change since then!!). Drove it for 130K miles total (from 110K to 240K miles) with only oil and brake changes.!!! I haven't even changed the timing built (which is crazy and wrong) but now after all these miles I feel like am going to drive it until it dies, but it's just driving perfectly fine which makes me think that maybe I should change timing built, sparking plugs, put new filters and other stuff maybe it could take me for another 200K miles who knows! I currently use the Lexus LS for long drives only or during winter when there is heavy rain or snow so I can keep my other cars including the W222 safe and clean with low miles too if I can avoid driving it for a long trip if it's not meant for fun or family time..

i use the S-class to commute to work, all family trips and all other daily activities. Enjoying it to the max... But I use the Lexus when I go buy groceries (feel okay to park it at Walmart tight between cars) or when i travel long trips to another city or state (for work only) when i travel by myself. There is really no reason to drive my s-class when i travel from one city to another 200miles for half an hour work/meeting once a week...
i’ve already put 74K miles on my S-class in less than 4 years, don’t worry about it 😅😂 am killing it already 74K
if i took my W222 for those weekly 200miles trips for that 1hr weekly meeting, i’d have ~120K miles on it instead of 74K now so i can enjoy it on a weekly boring trip by myself.... imagine the service and depreciation value for 74K vs 120K W222....? Does it make sense? Sometimes we have to be wise with how we use our assets.

To confirm comment above re depreciation, when I bought my 15 S550 in April, it had 6,200 miles and I gave less than 40% of MSRP.

Regarding 40 MSRP, do you mean 62K miles or 6200 miles? 6000 miles only for 40% MSRP (like $45K USD) seems pretty low (unless you meant 62K miles).

6,200 mi is correct. It was in a private party transaction, in which I paid asking price. Which I believe the gentleman had determined from talking to two dealers, including one MB dealer.

are you saying you paid 40% MSRP (like around 45K USD) for a 2015 W222 with 6000 miles only on it? Unless it is the base model with no accessories or options then I think that seems really low and below market value. Seems like you beat that guy really hard with that deal. 6000 miles on 2015 W222 with interior/exterior options is certainly in the 50s (50-58K USD minimum) As a fair deal. 6000 miles is like nothing.
