Correct- even Germany began to implement it!
There is a thread somewhere on it IIRC
Anyway, check fluid condition and implement a change strategy!

Above Flowrider mentions that the ABC fluid should be changed every 2 years , I think I am correct in saying that this requirement was never done by MB in this country so it is possible it has never been changed .
The 2 year change has come about more recently in this country by concerned owners / Independent specialists .
I think I have read that MB Europe did this 2 year ABC change ( but not us ) .
Hopefully someone will chime in with the accuracy of the above statements .

Correct on the MB UK thing. 2yr/ 24k came out of the USA after Pentosin themselves got involved, from what I've been able to determine.

£16/ litre for Pentosin CHF.11S and £24 for a 3mu filter, you'll need 9-10 litres for a full flush.

Edit on LK's post, at >70mph the ABC ECU will lower the car to its next lowest setting.

Lovely car and at least you now know what the potential downsides are. Depends on your maintenance budget I suppose. Perhaps add a few grand to the £20k purchase price and set it aside for any future problems! ;)
Srdl: Thank you for your caveat in regards to future costs of maintenance.

SBC is the braking system.
ABC is the suspension system.
In broad terms ABC is development of the Citroen oleo-pneumatic system used in the XM, CX, BX etc cars but with far more control.
The system consists of a pump, struts, gas spheres, a valve block, sensors and ECU.
According to information received from the sensors (height, acceleration in both lateral and longitudinal direction, braking effort (from SBC) and rate of strut movement) the ECU adjusts the pressure in each strutto keep the car level.
On the centre console there are two SVC switches. One changes from comfort mode to Sport mode and the other provides the ability to lift the car to clear kerbs etc. There are 3 height settings. Normal ( no lights on), medium (one light on) and high (two lights). Each press cycles through to the next setting (low, med, high, low...) ABC will also lower the car slightly at speed.
Lost Kiwi: Thank you for your complex, but quite understandable explanation of ABC = Active Body Control and SBC Sensotronic Braking System which is greatly appreciated.

Apologies, I fell asleep without answering!
However LK has explained in depth..
Just so you have some more understanding ..
ABC = Active body control
SBC = Sensotronic Braking system
Easy to get those mixed up!

John: Thank you for your explanation on ABC and SBC which is greatly appreciated.

Craig: I am awaiting a call from the vendor which I am hoping will be tomorrow. At least when I view the machine, and thanks to the generous response from members of this Forum, I shall be in a far more confident position than I would have been had I not sought advice. So we must now wait to see what the morrow will bring.

John, It's a little after ten o'clock and I have just received a telephone call from the vendor. He explained that he is presently a little pressed for time due to a hand-over of a car and one or two other matters of a pressing nature. He is to telephone again later in the day when he will have the time to explain the car in detail. For the present, the vendor has advised that the machine has had eight owners and this does rather concern me. He also said that they know the car well having sold it to the most recent owner; they also sold it to the preceding custodian. My anxiety about cars that have been in the hands of numerous owners is that some owners may not always have had the long term interest of the machine at the forefront of their minds, and therefore may perhaps have handled the machine in a harsh manner which may impact upon an owner some distance down the road. I can also understand that any machine should be judged on its merits and I doubt that the vendor, having sold the car twice, would wish to risk his reputation by selling a machine that has questionable integrity. What is your view, please, on cars that have been in mutli-ownership? Furthermore, what is the general opinion of others on this Forum in regards to this question? Thank you to everyone for helping me on this matter for which I am most grateful.

I can understand your concern about 8 owners , but sometimes this can be different family members that ups that number .
How many people can actually use 100% of that engine power ? More damage could be done to a 1.0 litre car driven at 100% .
I would look at service history , gearbox ATF , and as has been said ABC fluid change , remaining disc/pad life .

Wighty: Thank you so much for your prompt response which is greatly appreciated. I am hoping to get further opinions from members of the Forum which will assist me in forming a balanced perspective.

Multiple owners on an SL is not at all unusual to be honest.
Mostly it's because some owners buy these with 'starry eyes' then the realisation of costs comes in and some bail out...my SL for instance had 5 owners before me

I've had cars with 1 or 2 owners and cars of a similar age with 10 or more owners.
In my experience there is little or no correlation as to reliability or long term costs between them.
Sometimes a car can have multiple owners as a result of doing the rounds of the family (my 500SL is in this category). Sometimes a previous owner may buy the car again (our SL500 is in this category). Sometimes a 'low volume trader' may end up on the owners list as well (I've had cars like that in the past).

I would say to look at any car on its condition, history file and 'gut feel'.

Hopefully with 8 owners they have shared the cost and kept the car well maintained. I found that a new owner generally spends money on a new, to them, car when they first get it so I would not be concerned by the number of owners just the condition and maintenance schedule.

Flowrider: Thank you for your kind response. And yes, I can see the logic in what you say; it almost makes a multi-owner machine more desirable and no doubt in the eyes of the vendor, more valuable. I can see future adverts for motor cars reading: "This is a really excellent Mercedes-Benz motor car with the extremely desirable virtue and enormous benefit of multi ownership; indeed this car has had twenty four owners in two years all of which have burnished it to the nth degree such that the paintwork is like wet-glass. All owners have changed the oil every fortnight. None of them have ever driven it in the rain. The first to see will buy :rolleyes:;) :) :D :geek:

As with many things I'm in 100% agreement with Alastair here. The number of owners is not proportional to the care, or rather lack of, that has been taken with the car. It could have had two owners from new, with the second owner skimping on maintenance and repairs for (say) 7 out of the 10 years of the car's age. for my CL, bought on 120k, I have MB service history and very plentiful receipts to 89k (and owner no.3). it was one or both of owners 4 & 5 who did the damage, as that is where all work records stop...

What you need to do is to view the car, give it a good once-over and most importantly a good drive. The M113 5.0 is a big, lazy engine that never works very hard at all in a car that does not fill one with the desire to throw it around country lanes in a boy racer fashion, coupled in this case with a big, immensely strong transmission that has just over double the power rating that that engine can put out... great combination. So, your potential issues will be rust, ABC, SBC, electrics and roof leaks in no particular order. If you can satisfy yourself on those points then everything else is fixable at not vast cost.
