Recently, I decided, on much reflection, to discard the Kia Niro, and purchase a large estate. The Niro is too small for the dogs, and whilst admirable in terms of quality and economy, is no fun at all to drive. It is entirely too competent and bland.

The quest was to find a large estate, petrol, of a certain budget. The list dwindled and shrank until three candidates remained. The honest Volvo V70, the charismatic BMW E61, and the unknown to me Mercedes S211. My wife didn't want a V70 (she would have preferred a 240 Torslanda) and the stories about the reliability of the V8 petrol BMWs put me off, even though I had previously owned a diesel saloon and loved it. This left the S211, and an E500 at that. I didn't want the smaller engine as I thought it would be slogging its guts out for no discernible effect.

When I first decided on this there were a few remaining, at budget or above. The closer I got to actually putting my hand in wallet the fewer there were, until only one remained.

I arranged to travel to test drive the car, press-ganging my mechanic father into a trip, up country out of county.

I knew there were a few details about the car that needed attending to - some paintwork issues (not a problem as I know of several very good paint shops) and a remote fob that didn't work (I figured this wouldn't be the end of the world and in all likelihood a battery would solve the problem). I also knew of the car's thirst for fuel. The owner had replaced some suspension components for its MOT in March, and the gearbox had been replaced 50,000 miles previously. As the car had done in excess of 196,000 miles I wasn't particularly worried about the thing falling to bits - my investigations had resulted in several people reporting these cars would quite comfortably do half a million miles.

We arrived the car was unveiled, we checked it over, and had a drive - everything was fine and I began, even at this stage, to understand why the large estate with a big lazy V8 is so cherished. A deal was agreed, which saved some me money, and the car was transferred into my name, taxed, and insured. And so began the trip home. First stop the fuel station to fill the tank. The owner had thoughtfully put in a thimble full of petrol which enabled me to get there. £90 later, the car was full and ready to go.

Heading out onto the M25 I was immediately impressed with two things, the ride which is pretty sumptuous, and the quietness. As I drove I fiddled with al the trip computers and gubbins. Ergonomically it is pretty good, although the windscreen wipers are a deliberately obtuse and counter intuitive operation, especially the rear one. The audio system is more than adequate, although being used to Apple Car Play in the Niro I forgot to bring any CDs.

We stopped for a coffee (my parents following me in their car) and to check tyre pressures, which were all good. The 17" wheels certainly suit the car - bumps are absorbed effortlessly and the car corners well enough without much wallow. I do wonder whether this era of car is the best compromise for ride quality v handling as my BMWs had 17" alloys and they didn't have a hard ride quality.

On the trip home I averaged just shy of 30mpg which I was happy with - I know it's not a Niro and I didn't misbehave much, although I did tire of overtaking a BMW 140 about seven times within the space of a couple of miles so indulged my right foot and then enjoyed the kick down and subsequent surge of speed. If provoked it gains speed extremely well, but otherwise pootles along very amiably.

The car arrived home, I eventually parked it (the parking sensor light display on the dashboard is certainly different) and went to tell my wife about my adventure.

The next day I dropped her to work and popped across to the local Mercedes Dealer to get the key sorted. Town driving revealed a judder on braking - the car had been stood for a while so I guess there is probably surface corrosion to get rid of. There was also a almighty rubbery squeak / groan when turning the steering wheel to manoeuvre out of my parking space (this did go after a very short while) so I am attributing that to the fact the car had been stood unused. I may also have detected the steering feels heavier turning right at low speed than it does turning left. As I'm not expert I don't what to make of this. There are no oil leaks, the coolant is perfect, the OBC indicates no malfunction (which is nice), and there is 9000 miles before "Service G', whatever bank account emptying horror that may be is. I had allocated money for tyres which the car doesn't need - decent rubber on the front and back and clearly changed in pairs which is always a good sign.

Mercedes replaced the battery in the fob which didn't do anything, and then quoted my £300 to replace the key. I found someone down the road who will do two for £350.

There is nothing more to report at the moment but I will be getting the car booked into the garage I work at to have a check over, and I have emailed the two local MB specialists with my findings and asked for quotes for a service to include oil and filter, spark plugs, brake fluid, etc etc just so I can start from new, as it were. I also think doing discs and pads is probably a good idea.

I have the sneaking suspicion that this car may very well cost quite a bit in the near future. I don't (really) mind spending money on it because all it has to do is last five years. I do wonder however, at what point it becomes a stubborn point of principal, and how much pained smiles and gritted teeth may play a part in my ownership of this magnificent, preposterous land barge.

The next step is replacing the keys next week and finding out what hidden disasters lurk.

More to follow....

Please, we need photos!

Sounds like a good start though. I have an E34 V8 and it's great, when it works. A touring version would be amazing. There is something starting to tempt me over to the land barge Mercs though.

As for your commentary, surely a missed joke is that your remote fob does not even remotely fob? Or maybe that's just my weird way of looking for a pun when there isn't one?

More photos when I have opportunity. Tomorrow it is going in to have a health check.

Hopefully the techies will determine the cause of the judder, which is lessening as the car is driven more, and also the motor sound that comes on periodically.

I fully expect a few issues to be found but have budgeted accordingly.

Fingers crossed it’s not too hideous tomorrow.

Excellent work. Large engines are just great. Waftability rules!

Looking forward to more and hope the check over goes as smoothly as it can.......

The report is in, and is as bad / good (depending on whether you’re a half empty or half full person).

Front Discs warped
Front brake hoses in poor condition
Rear diff leak
Engine oil leak, excessive
NSF track rod end excessive play
NSF outer CV boot leaking

Tyres need changing

The A/C condenser described as being in poor condition but works preposterously well.

The advice is to get the the engine cleaned and then run to determine what the leak is (an ex Merc service adviser who I know and has seen the report suggests it’s most commonly the rocker cover).

I’m tempted to get the brakes and track rod ends and CV boots done first because oil can be topped up.

I’m not sure I should get the keys done until I’m sure the car is a long term concern.

An interesting quandary!

Very nice, I'm tempted myself with something like this.

Is this 4 wheel drive or is it a mistake

'NSF outer CV boot leaking'

Quite right! I’d misread the report without thinking of the implications.

The service bloke wants to clean the engine to determine what is causing the oil leak, but I’m going to get the brakes, track rod ends, CV boots and brake hoses sorted first, and if the leak needs topping up then that’s what I shall do.

Well done OP and thanks for starting a thread on your ownership. Two/three others have recently taken ownership of an S211 E500 and have yet to oblige, which is a damn shame!

Oil leaks aren't good and potentially dear. I would imagine that the first two in the list below (that I have had to address over 50k miles on the same engine) would be described as 'slight' and the third would be described as 'excessive'.

- cam cover (one to 1.5 hours labour)
- engine oil cooler (one hour)
- rear crankshaft seal (about seven hours)

The leak from the latter flooded my O2 sensors (as it was ignored for a few years by at least the previous owner), the oil was then released when the O2 sensors were unplugged in order to replace the engine and gearbox mounts, was drawn up into the ecu via a faulty design of crimp on the joint to the O2 sensor and caused a misfire. Phew! That was costly and it was the second indy that diagnosed it after I told the first where to go.

Looking at the MOT history on yours, (which popped up on my 'saved searches' a while ago and the VRN is oddly memorable!), it seems to have had some sort of oil leak from 2018 and 173k miles. It could be that the oil is an accumulation of the 'slight oil leak' or something a little worse.

Front discs/pads (1.75 hours)

I'm no mechanic, but if the track rods need replacing, won't that cause the wheels to wander/shimmy and potentially cause uneven wear on the discs/pads and potentially warp them?

With regards to the 'long term concern', it's good that the gearbox was replaced; hopefully it should be good for another 100k. Mine was replaced at 155k (the cost was quite eye watering). As for the remainder, it's rather a case of trigger's broom, once you begin to enjoy the 'suite' of attributes that this car possesses.

- invisible to police
- 105mph at 2,750rpm
- adjustable suspension
- space and comfort
- waft and teutonicness
- rust isn't a major concern
- changes up to seventh at 130mph hehe
- kudos of a rare model

I find my folly utterly irresistible and is the 'one car to rule them all'.

Personally, I would save the money on the 'known' consumables for the service (oil, sparks etc) which in all likelihood have been done. I would rectify the known issues immediately, the logic being that you can establish a good baseline of performance from which any deviations will be evident rather quickly. I'm at the stage now where I identified the rear wheel bearings starting to go aaaaages before the indy confirmed that they needed replacing.

Good luck, I'm following with interest.

Well done OP, I also drive an S211 albeit an E55, came to it from an S124 which was a tough act to follow.

I'd recommend getting the geometry set up, they do go through suspension components and it's well worth finding a good local MB specialist.

I do like the comment above - 'one car to rule them all'. Really not sure what I'd replace mine with - it's that good.

Thanks! It's not as bad as I feared. I have at my mechanics who like to work in their own time, enormously beneficial, and an ex Mercedes main dealer service adviser who felt there was nothing too dramatic about the list of ailments.

As for the work, I'd guess that the warped brakes are a result of the track rod ends having too much play, which is why they're on my list with the discs and pads. I'm also going to replace all four tyres (going with Uniroyals as I have had much success with them in the past).

I'm going to put aside there equivalent of the rentals and fuel for the Niro (£300 a month) for a Mercedes fund which I'll dip into when necessary.

Therefore my activity will be, in order

Brakes, track rod ends, brake hoses, brake fluid & tyres
Oil Leak investigation
Keys
Paintwork
Reluctant sunroof (I detest sunroofs but my wife likes them so it had better work)
Oil & fluids change & spark plugs
AC Condenser replacement (at some point)

Then as final a hurrah probably the power steering pump.

I'm happy for the garage I work at to do all the work, with the possible exception of the oil leak, because as the service manager told me 5.0l V8s aren't common enough for the techies to be familiar with. Luckily there are two specialists nearby - one of whom got in touch immediately and were extremely professional and the others who have replied to enquiry about replacement keys I made in an email primarily about the work I've detailed here, and haven't bothered replying to my follow up about approximate costs for the other work!

Chatting to my mechanic father this morning, this is actually getting a little bit exciting.

Thank you!

I have got the car booked provisionally with the professional specialist, so I will have them sort the suspension geometry and have a decent look at the oil leak. That keeps my techies at work happy with the bits they do, and keeps me happy that people who have experience with such daft machines are looking after the oily bits.

Is the action with the 'reluctant sunroof' to do with the 'auto opening' action when closing?

With regards to geometry, perhaps by the age of your vehicle there will be wear in the air springs all round, which means that a fluted adjustment bolt will be necessary to offer the range of adjustment necessary on the camber and castor.

The reluctant sunshine roof! It opens and closes, but sticks doing so. I think silicon spray is what’s required for the rubber bits as the motor’s clearly working but something in its travel is causing too much friction.

I loathe the things so if it doesn’t work that’s perfectly fine by me, but my better half will love it so I it really ought to work. L

Glad to see you took my steer from the Merc thread. They are a lovely car when setup right. I think you've prioritised well the work list.

Micheal and others will be able to advise better than me as he has an E500 and if you haven't read his owner's blog then it's well worth reading. Lots of good photos.

Enjoy.

Sunroof... the correct MB part is

Synthetic grease, sliding roof 500g, DB supply specification 6827.60

A0019894651

However, there is also another product which I have seen on ebay.

The telescopic (?) or extendable visors require lubing too, periodically.

Thanks for the recommendation. With a little work and a fair amount of money I think we have found a car that will do us for the next five years or so.

I’m quite looking forward to reporting on what’s going on and how the car is progressing.

Guilty as charged, but if I were to post in real time the glacial rate of progress on my E500 may make people think they’re complex beasts! Perhaps a catch up thread when it’s done.

The fluted bolts are for any 211 (or indeed 219) - it gets rid of the “they all do that sir” excessive wear on the inner tyre edges caused by the standard factory camber setting (I can never remember whether it’s -ve or+ve when they lean inwards). My car is getting new front struts but will also be getting the bolts at the same time.

5.0. The car was under our budget, which does look like after the work that needs to be done may be broken, but should result in a car which sees us through the next couple of years.

Looking forward to getting started on the new project. My dad, a veteran of many seemingly foolhardy vehicular adventures, is more excited than I am!

Most of all I’m excited to drive the car once the track rod ends, brakes, and tyres are sorted.
