The 560SEC sat at the top of the Mercedes-Benz range in 1987. In Australia, that equated to a dealer price of over $215,000 before taxes and other costs. This was more than double the median house price in Sydney/Melbourne. Consequently few were sold in Australia, although their exclusivity means survival rates are quite good.
The SEC was launched in 1982, ostensibly replacing the W107 SLC range. In reality, the SLC is based on the SL and the SEC is based on the W126 S-Class. It’s more the spiritual successor of the W111 Coupe. The original range consisted of the 380SEC and 500SEC. Mercedes Benz Australia in their wisdom at the time decided to comply the 380SEC with local regulations and not the 500SEC. This resulted in a large number of private imports from countries like Hong Kong, Singapore, UK and so on.
The W126 was face-lifted in 1986. As part of the face lift, the 380SEC was replaced by the 420SEC, the 500SEC was improved and the new range topper, the 560SEC was added. Australian delivery models were subject to local regulations, which meant detuned engines (both for Australia’s poor fuel and pollution regulations).
The W126 SEC is generally regarded as one of Bruno Sacco’s greatest creations. It is a big comfortable cruiser for four people and is extremely elegant for such a large car. It was packed with the latest technology of the day including options for airbags, ABS brakes, traction control, heated seats and so on.
About this car
This car is a 1987 Mercedes 560SEC ECE. It was sold new in the United Kingdom. This means it has the 220KW engine, vs the 182KW version offered in Australia. This is shown up as option 822 below. Option 822 included 10:1 compression, different cams, exhaust system and a tune for higher octane petrol.
Apparently this car has had only two owners since new. It was imported from the UK into Queensland in 2005. While in the UK it wore the registration B1 SWS, which I guess was a personalized plate. Later in Queensland it was registered under 737 VHB. The last owner was in Esk, Qld. Esk is in the outskirts of Brisbane.
As you would expect with a car sold in a cold climate, it is equipped with heated seats. The heated seats work well. The car also has orthopeadic seats. These are for people with a bad back and allow fine control seat comfort via a series of air bladders in the seat back. This feature is still fitted but no longer works. I presume there is a leak in the air bladders or lines, as they controls no longer work.

I’ve now owned three of these cars over the years, the most of any Mercedes Benz Models. This includes this one, a 1987 Mercedes 560SEC ECE as well as 1988 and 1989 models. The 1989 model was quite rough but the 1988 was a lovely car.
What’s Next?
Over time, as well as maintenance on this car I would like to do a few upgrades:
I recently purchased a Mercedes-Benz 560SEC at auction. The auction was in Queensland, so the cheapest way to get the car was to have it shipped to a depot in Bathurst. My brother and I went ...
I spent the afternoon going over the 560SEC, making small improvements and evaluating the car. The first order of business was to look at the original factory wheels that came with it. As was ...
Today I continued working on the 560SEC. I gave the car a quick wash to get a better sense of the condition of the paint. Overall it is pretty good for its age, with the ...
My 560SEC came with a set of aftermarket wheels from Simmons. The Simmons wheels are a locally made wheel, and this set are two piece 16" variants. They are shod with 245mm tyres so ...
My 560SEC came with a set of Simmons wheels. These wheels are not to my taste and were too wide for the car. The wheels had been mounted with spacers which I do not like. ...
My two biggest concerns buying this 560SEC was the potential for rust being a UK car, and the condition of the timing chain. I was pleasantly surprised when I looked underneath the 560SEC and found ...
I've been preparing for the next round of improvement projects for the 560SEC. The most important is the Timing Chain and Valve Stem seals. I'm not going to do this job myself and am ...
When I last used my 560SEC before Xmas, I noticed a rather large puddle of petrol underneath it. I've not driven the car since as it is rather dangerous to drive with such a leak. ...
The Timing chain replacement is almost finished on the 560SEC. The new chain is installed, guides fitted and valve stem seals replaced. I stopped by the workshop to pick something up that I had ...
My 560SEC had a problem where it would emit a puff of smoke after idling. This was rather embarrassing taking off from the lights. It did give me the advantage of keeping people back who ...
All W126 models have an insulation pad under the bonnet to protect the paintwork and reduce engine noise. Over time, the W126 bonnet insulation degrades and starts crumbling down onto the engine. At ...
A common feature of Mercedes cars from the mid 70s through the mid 2000s is the self-leveling rear suspension. This system is standard on the wagons, but was commonly specified on the higher end sedans ...
One of the things I noticed when I first changed the oil on my 560SEC was the dent in the lower oil pan. Presumably it hit a curb or rock at some point. It ...
It was just announced that the NSW 60 day logbook 'trial' has been made permanent. This is great news as its a really good system. The two minor drawbacks - the amount of paperwork and ...
The MBCNSW held a tech day at a dyno equipped performance shop today. I was keen to attend as I wanted to understand how much power my ECE 560SEC is making. Geting dyno time independently ...
I discovered at the MBCNSW Dyno day that my 560SEC was running dangerously lean. Lean enough to cause damage to the engine. While I was in the USA for work, I went to the Mid ...
When purchased, my 560SEC did not have working climate control. Not only did the A/C not work, but the heater had a mind of its own, occasionally bursting in to life and turning on full ...
Once I got the air conditioning working on the 560SEC it was apparent the auxiliary fan was not working. As can be seen in the wiring diagram below, the W126 SEC auxiliary fan can be ...
The W126 was the first Mercedes to feature plastic cladding. I'm not sure this is the best feature of the W126, but it started a trend that would continue for many years. The W126 ...
One of the things that had been bugging me about my 560SEC was the missing W126 antenna grommet. Over time, they perish and instead of replacing it, the previous owner had used household sealant. This ...
Over the years my 560SEC has acquired quite a lot of stone chips on the front of the car. I understand the previous owner was in semi-rural Queensland so there may have been some gravel ...
My 560SEC has been having a couple of problems with its cooling system. Coolant has been weeping out of the top tank of the radiator. In addition, the monovalve has failed, causing unwanted heating at ...
My 560SEC had been leaking coolant and giving me heat when I didn't want it. Last week I started the repairs for these problems. As the Bosch and Mercedes W126 Monovalve repair kit was no ...
As part of the work I have been doing to the 560SEC, I have removed the radiator. The radiator was leaking from the top tank and appeared to be original. It was an IMI unit ...
My 560SEC has been leaking from the power steering and self leveling suspension. In both cases, it is obvious that (at least some) of the leakage is coming from the low pressure hydraulic hoses. ...
I have been working on a project to eliminate the monovalve from the climate control system in my 560SEC. In the last part I had almost completed the cooling hoses required for the job. I ...
As part of the installation of the Monovalve elimination kit, I needed to remove the ABS controller bracket. The bracket was in the way of the coolant hoses. I order to remove it, I needed ...
I had previously removed the W126 cowl covers to clean the drains. Now they are clean and I have replaced the ABS module bracket, they were ready to be re-installed. Before I did so, I ...
Today's job was installing a W126 radiator into my 1987 560SEC. I had previously sorted out the cooling hoses as part of my monovalve eliminator install. I was just waiting on a few extra parts ...
I have now completed the installation of the Movovalve elimination kit on my 560SEC. So far so good. Most importantly, I don't have heat when I don't want it, but it is available when needed. ...
A couple of months ago I tried a modification on my 560SEL to trigger the auxiliary cooling fan earlier. The primary reason for this was to provide adequate air flow over the A/C condenser in ...
A couple of months ago some of friends of suggested a group order for Cocomats. This coincided with a 15% off sale and shared shipping. Cocomats are a floor mat made from coconut fibre and ...

I've had the AMG Aero I wheels ready to go for a couple of months. I couldn't fit them until the Penta wheels were on the 450SLC. The reason was that I wanted to use ...
I attempted to attend the MBCNSW May night drive with two separate cars. Coincidently, I had the same brake issue with both cars. On both cases I experienced a soft brake pedal, and on further ...
In the two years of owning my 560SEL, one of the things I have appreciated is the original Becker CD player. I've owned many classic Mercedes-Benz models over the years, but until the 560SEL none ...
