Age of ownership.
I’ve had my s550 sport for 4.5 years almost. 100-128k miles. $13000 or so in repairs and maintenance. Car is mint.
I’ve decided to keep the car for as long as possible. W222 never really appealed to me that much and m278 bore score is headache I don’t care for. Those are not 100-200k cars like previous S class.
w223 is in another league of problems. So I’m left with no car I’m really that crazy about and since my cars are hobby cars ( I take train to work and we do have a Lexus for family duty ) I decided to keep mine for as long as I can. Resale values are laughable and I rather keep it in mint condition and enjoy it.
I toyed with an idea of getting an off lease w223, but the depreciation on those cars is just scary. Even with a car warranty, it’s a bad financial move. And is it or that much better than a w221? To me no. Needless complexity galore.
I’ve had Lexus LS cars before and I thought about getting a newer ls500 but I just hate the way they look. Maybe a last year ls460 I thought, but I had a 08 LS and it was great car, but I already had it.

I do plan to drive it daily for at least 10 more years.
Generally I was never one of these types that change cars every 3 years to keep up with the neighbors.
I maintain my cars at the dealer, I use only genuine parts, and I replace things when they start to make noise i.e. at "Phase I" of going bad.
I don't care about the costs. I just don't want to buy another S class. I love my W221, I love the fact that it's non-facelift, and I appreciate that I bought a M272 and I get 11L/100KM mixed highway/city year after year.
I know it's faults, I have fixed everything (balance, 7G, intake) and I'm fine with it. It's not a W140, I know.
It's not even that I have "too much" in the car to sell it, I just don't feel that replacing it will bring me any additional happiness.
I don't love any material things, but I can say that I do, really love my S350. It's not exhilarating, it's not exciting, it's not "push you back in your seat", it's just a LWB S class that has made me happy enough to say "I'm good".

as for ANY engine block with electroplated bores - they are all temporary loaner vehicles designed to give up
currently on Hols with access to two toyota's - everyone here thinks they are the best cars of any available and think they are some impregnable fortress of reliability
the hilux is a 2008 (but bought new in 2011) 3.0 D4D tractor - it handles like a pig, has stupid heavy power steering with almost no steering lock, has suspension for 1000kg more then it ever has in it even with 7 onboard, the brakes are horrible, the 4 speed auto has 3-4 ratios too little, the diesel rattle is horrific, its drinks like a fish, the centre bearing fails because the prop shaft expansion joint (to accommodate length change with the live axle bouncing about on leaf springs) seizes up, so all the forces go into creating acute angles on the rubber bush of the centre bearing. At 117 k miles (189k KM) everyone thinks its baby and claims they should do 300k (500k km) on its cast iron block engine - but no one seems to be aware they only fitted pistons that work for model year 2014 - any earlier ones crack - so if you open the throttle you may have armageddon at any point
the other one is a 2005 corolla zzr120 - its got stupidly light power steering - that's fantastic, and exactly what the w221 always needed !!!, add in the most crazy soft suspension married to dangerously nervous handling, its quite entertaining to chuck around - even with a super gutless, but incredibly flexible1.4ltr VVT 4 pot engine.
Never owned or worked on toyota's before - they are so overly complex and so crap in many areas its an eye opener, there is nothing about their engineering that is right
wrong length bolts, wasting metal and adding weight
5 rubber sections and 4 steel pipes when it needs a simple length of vac tubing on the engine - why ?
same terrible design as many others with alloy heat shields held up with tiny steel fastening - creating a galvanic reaction rotting the alloy
door check straps (8 across both cars) of an identical design that don't have any workable detents - so car parks are a danger, as is trying to get out on a slope
both have headlights that basically do nothing at all - although the corolla at least gets 4 lights on high beam like all cars need
but they have one redeemable feature - neither have flash seats, not even lumbar, let alone squab adjustment on the seats - but both give NO back issues whatsoever ! even on 13hr non stop drives - and are more comfortable than any fitted to any German vehicle in history !!!!

Re: the seats comment. Try the 2019-current Cayenne 18-way sport seats. Best seats ever. Well bolstered and fit like a close fitting bespoke tailored suit.

Just picked up a 2010 RWD with 133k on it. I’ve had an x164 for the last eight years and before that a w211. At this point, I viciously DIY everything and this vehicle will never see the dealer.
so far I am into it for $500 for motor and trans mounts, lower control arms, all filters. I’m expecting to replace carrier bearing and flex discs and rear trans seal while I’m in there. The aux battery is also probably factory so that’ll need replaced.
I’m on the very opposite end of the spectrum from some of you who dealer maintain - if it isn’t important and is broken, it will either get a $0 fix or stay broken. At this point I consider this car close to fully depreciated but still a very nice ride and an even better looker.
The plan is to hand it off to my new driver in five years and move on to a 222 with the v12.

Do you have a lift to work on the car?

i’m gonna do the engine mounts like this, but I have a buddy with a lift for when I do the center bearing, if I need it.
i’ve got some other pics posted over in my buying a 2010/2011 thread of the trunk in various states of disassembly and I’m going to continue my maintenance thread there.



I still have my iridum silver 2007 S550. It now just went past 300K MILES on the clock. I bought it from the MB dealer with just over 100K back in 2012. In the intervening time I've replaced 3 airmatic struts, starter, lower control arms, engine and tranny mounts 2-3 times now, fuel pump, and usual wear items like brakes and bulbs. Recently had the timing chain replaced but that is not a surprise given the miles. Engine runs so smooth and quiet. Overall, Mercedes W221 ownership very reasonable in terms of cost. I still get oil change service at the dealer and take it to trusted independent shops for repairs. I have been VERY fortunate to know good mechanics who don't charge an arm and a leg. The car is my daily driver to work and given the age with some scratches and dings here and there, it's the 'beater' car in the family. I take it to downtown San Francisco without worrying about what the riff raff may do to it so I have that peace of mind with this car. The car goes when the car/engine or I die. I do not intend to go first.
Also had a W222, but there was not enough trunk space for two sets of golf clubs with all the electronics behind the rear trunk panels so traded it for a GLS. I love the W221 so much I jumped on the opportunity to buy a fully loaded magnetite black (gorgeous color) 2012 4-matic with B&O sound system, 4 zone climate, rear reclining seats, night vision, distronic plus, etc. It is in perfect condition. I drive it on occasions like our recent trip to Pebble Beach Resort.
Still contemplating a W223 inline 6 engine powered S500, but the ipad screen and loaded technology is not a something I really care for at middle age. You learn in life that having too much (of anything) can sometimes be a burden. The W221 is all I need and being grateful for the wonderful experience of driving an S-Class is enough.
have you read out your engine number?
glad to hear the usual suspected parts are the ones that need constant replacing, such as suspension components, etc.



Bits of gear teeth found during timing chain replacement.
Where’s the teeth???
Beautiful day driving a high mileage S550







My future BIL’s M273 W221. Thought he was messing with me when he said “it has about 500 on it.” Taken last Thanksgiving so probably closing in on 500k.



At what mileage did you discover this?

What year and how did he rack up that many miles? The ‘E’ in the lower right corner tells me it’s not an earlier model. I only have ‘C’ or ‘S’. Glad to see that many miles can be attained for a W221.
