BUYING GUIDE
No. 162
The W123 is a superb family
classic. There are safety features
galore, and with rear seatbelts
it’s ideal. The diesels offer good
economy, as does the 230,
which gives a better
compromise between
performance and mpg than
the 280. The estates are
vast, and if you find a good
one it’ll be an excellent
load-lugger. Seats are far
more adjustable than
other cars of this age,
the driving position
offers great visibility, and
there are all sorts of
features you wouldn’t expect to
find on a car this old.
What can’t it do?
Umm… well, I suppose you’d
have to say the 280 is a bit
thirsty. Talking of fuel, some
sources say the engines aren’t
keen on regular unleaded, but
other owners have said they’ve
had no problems.

Mercedes W123
Take your time to find a good one, and this could
well be the ultimate classic saloon.
Production
Timeline
This will get you an excellent
low-mileage saloon that’s been
properly looked after – either
original or restored. Genuine ‘as
new’ examples can be twice
this amount, though.
Condition 2 – £2000-£4000
Should get you a solid, usable
car, but it might need minor
work in the near future.
Condition 3 – £500-£1000
Potential basket cases that
might only be worth whatever
someone thinks they can sell
the parts for. You might get
lucky, but you’re better off
spending more in the first place.
Possible upgrades
Such was the development
behind the W123, there’s very
little you’d want to do to try to
upgrade them, and so there’s
not much in the way of extras
on the market. Sensible options
are powdercoated components
such as rear trailing arms and
battery trays.
All standard annual maintenance
can be done by a DIY enthusiast.
Access to the engine bay is
superb, and the systems on the
W123 are pretty straightforward.
The 280 models are slightly
more difficult to look after, being
a DOHC six-cylinder engine with
lots of tappets to sort out.
The fuel injection system’s
reliable enough but you might
want to go to a specialist to
check the flow pressure. It’s
worth using Mercedes filters
when you carry out servicing.
They’re only slightly more
expensive than aftermarket
ones, but you’ll have greater
peace of mind over their quality.
Oil changes should happen
every 4000 miles, with the
timing chain needing to be
changed every 50,000 miles.
Brake fluid should be flushed
regularly to avoid corrosion in
components. Replacing calipers
and the master cylinder can
quickly get expensive.

go on building cars in the same
way as the W123 would have
become prohibitively expensive.
But while they’re beautifully
engineered and the build quality
is outstanding, these cars are
now all more than 25 years old,

immune to degradation. And
being an expensive car when
they were new means they’re

The W123 was a rare car in that it had a waiting list
all through its production life.
Interior
CM says…
Engine
The W123 came with 11 engine
options. All last well, particularly
the diesels, but you’ll need to
check the paperwork to ensure
that the oil’s been regularly
changed and that the timing
chain has been replaced at the
correct intervals.
A cylinder head overhaul for a
280 will be expensive, but if the
worst happens an engine rebuilt
using Mercedes parts and coming
Seals
Check the rubber window seals all round for
cracking and degradation. They often fail,
allowing water to leak inside. Replacements
for the door glass are about £25 apiece, and
will help save the doors themselves.
with a warranty will cost about
£2500 from W123 World. Check for
evidence of oil leaks, and look at
the condition of the hoses.
All diesels will smoke slightly
when cold, but it shouldn’t be
excessive or continue once the
engine’s up to temperature. They’ll
sound like a typical diesel of the
time, so they’re not quiet, but any
hollow knocks or rattles are signs
of potentially expensive problems.
Mercedes fine-tuned the
exhausts on injected models for
the best performance and noise
deadening. They were also made
from 14-gauge steel. Aftermarket
ones generally rattle, the back
pressures aren’t right and they
don’t fit properly. Basically, don’t
fit a cheap one – or a stainless
steel one. They’re too thin, the
noise resonates inside, and they
also don’t fit very well.
Trim
There were five trim options: MB-Tex,
velour, leather, half cloth or full cloth.
Interior trim is very hard to find. It’s not
worth your while buying anything
needing a retrim. For example, new
original MB-Tex covers from Germany
are nearly £2000 – plus fitting.
The widely adjustable seats are generally
comfortable and were designed to be
relatively firm. However, a collapsed
driver’s seat is a common fault, and can
make the car’s handling feel ‘wallowy’
when it isn’t.
!
When the W123 was new, the
paint was an industry
benchmark. However, it isn’t
available in its original form
anymore and it’s difficult to
match. The paint finish is one of
the most critical and expensive
areas if you want to restore a car
– it’s where all the hard work
can be lost.
All the original panels are still
available – a front wing is £260
from Mercedes. While you can
get a pattern wing for £50, they
don’t fit and rust badly. Cars built
from 1976-81 used recycled
steel so they rust worse than
later ones.
Sunroofs can leak. Lift the
carpets and check the condition
of the floorpans. The drain pipes
coming down from the sunroof
rust out, so water gets into
places it shouldn’t. Getting a
replacement sunroof is £1200
– it’s a three-man operation that
involves removing either the
front or rear windscreen.

The W123 is amongst the UK’s

“I bought my first
W123 in London in
1979. It was one
year old and cost £6650 when
a new house in Swansea was
£10,000. The taxi driver said ‘but
a Mercedes isn’t like buying any
other car’. I’ve owned, hired,
serviced, dismantled, and now
fully restored every model over
the past 31 years.
“They’re wonderful cars. Sadly,
prices of new original parts are
now equally wonderful. They’re
tough, and quite easily the finest
engineered car of the 20th
century – they had no real
competitors at the time.
“If you buy a restoration
project, it really has to go to a
Mercedes specialist – preferably
someone who’s already painted
one – and always see some of
their work first. I can’t emphasise
that enough.”

The bottom spring mount on
the trailing arm can fill with salt
and debris and rust through. To
sort that out, the whole assembly
will have to be removed. To
replace that section, which also
carries the hub, will cost in the
region of £1200, while the
crossmember that also forms part
of the rear suspension will be
about £300-£400. Removing the
rear wheel bearing involves the
use of a special tool.
Check the rubber suspension
bushes and the driveshaft
rubbers. However well put
together a car is, rubber degrades,
and any failures here could be
disastrous. The estates models
have self-levelling suspension,
which involves
different dampers.
Despite being much the same
layout otherwise, replacing them
is very expensive – budget for
about £2000.
There were seven different
springs for the W123 depending
on the spec of the particular
model. If you need to replace
them, it’s not an easy job to begin
with, but don’t be tempted to buy
a cheap aftermarket ‘off-the-shelf’
spring. It might be for a W123, but
a fully loaded automatic 280
instead of a manual 200. If so, it’ll
be miles out and will ruin the way
the car drives. Check the part
number and fork out for the
original components.

Mercedes never fitted budget
tyres to their models. The W123 is
a lot of car, and if you’ve got a
cheap tyre on there it’ll also harm
the handling. Decent rubber can
transform a W123. The front
anti-roll bar mounts can be
