## The story

*What this car is, and the six questions that decide whether the one you are looking at is a good buy*


## 1 · Who built it, and what they built

The W211 E-Class was shown in January 2002, drawn under Peter Pfeiffer, who had taken over as head of
design from Bruno Sacco. It is a deliberately quiet car: four doors, a boot, twin headlamps, and
nothing in the shape that argues with anybody. That restraint is the whole point of what follows,
because what Affalterbach did to this bodyshell has almost no external evidence.

Affalterbach is AMG. In the years this car was built the company was half inside Mercedes and half
outside it: DaimlerChrysler bought 51 per cent of AMG on 1 January 1999, and only on 1 January 2005
did the founder sell his remaining shares. So the E 55 comes from the period when AMG was a
subsidiary that still ran its own engine shop.

### The engine

The M113K is a 5,439 cc V8 with an aluminium-silicon block and aluminium single-camshaft heads, and
**two spark plugs per cylinder** — sixteen plugs in the car, which is worth knowing before someone
quotes you for a set of eight.

On top of it sits a screw-type supercharger made by IHI, of the Lysholm design: two intermeshing
rotors, driven off the crankshaft through an electromagnetic clutch, so it can be switched out of the
drive when it is not needed. Not a turbocharger. Nothing waits for exhaust gas. The air it compresses
is cooled by two intercoolers with their own water circuit and their own electric pump, and that pump
becomes one of the six questions later on.

**476 PS at 6,100 rpm and 700 Nm.** In 2003, in a car with rear doors.

### And the gearbox, which is the best detail on the car

One transmission, the five-speed AMG Speedshift. No manual was offered, and — this is the part people
get wrong — no seven-speed either, although Mercedes had just launched the 7G-Tronic and put it in
lesser E-Classes.

The reason is a number. The five-speed AMG used is rated to **1,079 Nm** of input torque. The 2003
7G-Tronic was rated to **735 Nm**. The engine makes 700. So the newer, cleverer gearbox had almost no
headroom, and the older one had a third to spare. Sometimes the old part stays because the old
part is the stronger part.

### How many there are

**14,437** were built worldwide across the whole run, and about a tenth of those were
estates. That is not a rare car in the way a homologation special is rare, and it is not a common one
either: it is a car you will find a handful of at any one time, in your country, at any given month.

### How the figures in this guide work

**How much work each job is, not what it costs.** Most points in this guide carry an effort — an hour
or two, half a day, a day, two or three days, or a week or more in the workshop — plus a line saying
whether the money sits in the part or in getting to it. Where a documented hour count exists for this
car, that is there too.

**There are no prices, and that is deliberate.** What a job costs depends on which country you are in
and which workshop you walk into, so a figure I cannot verify is worse than no figure. If you want
money, ask any workshop one question — *what is your hourly rate?* — and every hour in this guide
becomes your own number, in your own currency. One question, and the answer is actually true for you.

None of this is advice about one particular car, because I have not seen the car you are looking at.
Have every one of them inspected before you buy, by someone who knows this engine.

## 2 · The six questions that decide whether *this* car is a good buy

These cars are now between twenty and twenty-four years old, and the difference between a good buy
and an expensive one has very little to do with the asking price. It comes down to six questions.
Four of them cannot be answered by looking at the car, and two of them can — if you know where to
stand.

**1 · The brakes, and whether they are still under warranty.**
The pre-facelift W211 has SBC, an electrohydraulic braking system with no mechanical connection
between your foot and the front calipers in normal use. The unit counts its own operations, and when
the count runs out it puts up a warning and is due for replacement. Here is the part almost nobody knows: in
2018 Mercedes-Benz USA **extended the warranty on the SBC hydraulic unit and a list of related parts**.
On a US car that can still be live, and it is the single most valuable thing a buyer of one can find
out — which cars it covers, and for how long, is in the buying guide. The notice is American; whether anything similar applies
where you live, only Mercedes can tell you. Either way it is a phone call with a chassis number.

**2 · The supercharger complaint that is three completely different bills.**
"It has gone flat" and "there is a noise from the front of the engine" are, on this car, three
separate faults with three separate prices, and only one of them is the supercharger itself. They are
routinely confused, and the confusion runs one way — the
cheap one gets diagnosed as the expensive one. Anyone quoting you a supercharger figure before those
have been ruled out is guessing.

**3 · The crankshaft pulley, which you can inspect yourself with the engine switched off.**
On this engine family the rubber in the pulley lets go with age, and if nobody notices it can take
the front cover, the water pump or the belt with it. It is the one significant fault on the car that
you can see for yourself, standing in front of it, and it takes ten seconds once you know what you are
looking at.

**4 · The suspension, which is priced per corner.**
Most of these have air suspension, and air struts are quoted individually. A car sitting level on the
forecourt tells you less than you think, because the compressor hides a slow leak all day — the
buying guide has how to see past it. And ask whether anybody has replaced any of the four already.

**5 · The gearbox, and one connector.**
The five-speed is a strong unit with two known weaknesses, and both of them are electrical rather
than mechanical — one of them is a single connector. Both are far cheaper than the gearbox that people
assume is failing when the warning appears.

**6 · What has already been paid for.**
On this car the odometer tells you less than the folder does. A documented 220,000 km with invoices is
a better buy than an unexplained 90,000 km, and that is arithmetic rather than sentiment: most of the
money in a twenty-year-old AMG sits in work you cannot see, and paper is the only evidence it happened.

### What the honest answer to all six looks like

On a car with history, where the known items have demonstrably been done, an owner gets through
**roughly half the list in the first two years, and none of it in one go** — not because things break,
but because things arrive that were always going to arrive. On this car that is genuinely a series of
half-days rather than one big bill.

That number is only useful if you know what it is made of. The buying guide takes each of these six
apart, adds the things that are simply twenty years old, and gives every one of them what the work
involves, what tells you about it at a viewing, and whether it has to be done now or can wait years. It ends
with a card you print and take with you, in the order you do it, including the three moments at a
viewing that come only once.

## 3 · Which years, which specification

The E 55 AMG W211 was built from **2002 to 2006** with one engine and one transmission: the
**M113K**, 5,439 cc, supercharged, 476 PS, and the five-speed **AMG Speedshift**.

**There was no manual, and there was no seven-speed.** That is your fastest filter on an advert. It is
also the answer to the question people ask about these cars, and the reason is in the previous
chapter: the five-speed was the stronger gearbox.

**And the model years matter here more than they usually do.** Two dates are worth holding on to:

*The 2006 facelift ended this car.* From the facelift the fast E-Class is the **E 63** with the M156,
a naturally aspirated 6.2. So a "facelift E 55" is not a thing — if the advert shows the later lights
and grille and says 55, look again at what you are being sold.

*SBC.* It was fitted to the W211 from 2002, so every E 55 has it, and it was dropped at the facelift
after customer complaints. There were two recalls on it, in May 2004 and March 2005, covering large numbers of cars.
None of that is a reason to avoid the model — see the warranty — but it is a reason to ask which
recalls this car has had.

**The myth to clear up, because this one gets repeated everywhere.** You will read that AMG never
built a supercharged engine again after this one. That is not true: the M113K itself ran until 2011 in
the G 55, and the supercharged M155 in the 2004 SLR McLaren came after the E 55 was launched. What is
true, and enough: **after this engine family AMG's mainstream V8 went naturally aspirated and then to
turbos.**

**Body styles.** Saloon and estate. The estate is about a tenth of production, drives the same, and
carries a dog.

**Check that it is a real E 55**, which on this car is mostly a matter of the engine bay: the
supercharger between the banks is not something an E 500 has, and the badge on the front wing says
*V8 Kompressor* rather than V8. There is also a chance of an AMG builder's plaque on the engine
cover — but be careful how you read it. The signature plates came in around 2003 and plenty of
M113K engines never had one, so a plaque is a nice thing to find and its absence proves nothing at
all.

Beyond that, look for a car nobody has modified. Factory wheels, standard ride height, the original
exhaust, no added wiring. Modifications are not automatically bad, but on a supercharged engine a
pulley change or a remap is a change to how hard the whole drivetrain is worked, and you would want to
know.

## 4 · What it is worth

This is the hardest thing to establish on your own and it does more than anything else to decide
whether you buy well. I am not going to give you a price list — it varies by country and by month, and
an out-of-date number is worse than no number. I am going to give you the method.

**Compare on paperwork, not on mileage.** A documented car with invoices tied to odometer readings is
worth more than a low-mileage car nobody can account for, and on this model the gap is unusually wide.
Air struts, the crankshaft pulley, sixteen plugs, the intercooler pump: none of that shows in the
mileage and all of it shows in the folder.

**There are three kinds of car for sale, and each one deserves a different offer.**

*The documented car.* Full history, invoices you can lay against the readings, and an owner who knows
when what was done. Asking price at the top of the market, usually justified. What you are buying is
the history rather than the car.

*The tidy car with no paperwork.* Drives well, looks well, and the owner says everything has been
done. The hardest of the three, because there is nothing to see. You buy it on the condition it is in
today and you budget the top end of everything in this guide.

*The project.* Known work, price adjusted to match. That can be an excellent buy if you know what you
are taking on and have the money available. Ask for a list of what is known — the owner usually has
one, and on this car it is usually the suspension.

**How to set the three against each other.** Take the asking price, work through both lists — this
engine's own faults and the age list — and add up what is coming in the first two years. Call that
the entry price. Then compare entry prices rather than asking prices. The most expensive car is
surprisingly often the cheapest.

**Where to look:** your country's big classified sites, the AMG specialists, and the auction sites.
Follow the market for a month before you go and see anything. You do not need to know what one is
worth; you need to know what is happening — which cars sell quickly, which sit for months, and at what
price.

**One thing worth carrying instead of a number.** The gap between the cheapest and the best of these
is wide: at the bottom are early cars with high mileage, and what you pay for further up is condition
and paperwork.

## 5 · What it is actually like to own one

Start with the thing you notice in the first hundred metres, which is that nothing happens. It idles
like an E 240. It pulls away like an E 240. The supercharger is clutched out of the drive when it is
not needed and the car is genuinely quiet, and then you ask for everything and 700 Nm arrives all at
once, from almost anywhere in the rev range, with a whine underneath it that nobody at the traffic
lights can place. Owners describe the character in almost identical words: docile, and then not.

That is a different sensation from a naturally aspirated engine and a different one again from a
turbo. There is no waiting and no crescendo. It is simply there the moment your foot is down, and it
does not care what gear you are in.

Then it goes back to being an E-Class. Four doors, a proper boot, rear seats an adult fits in without
negotiating, and a ride that on air suspension is genuinely comfortable. Nobody looks at it.
Colleagues do not know what it is. Of everything this car does, that is the part owners talk about
most — that it is a very fast car that asks nothing of you socially.

**What it costs you in attention.** More than a modern car and less than you fear. It wants its
service history kept up, sixteen plugs at the right interval, the air suspension watched, and tyres
more often than you are used to — they are wide, they are AMG sizes, and a set is a real number. It
does not want to sit still for months; nothing on it improves from standing, least of all the air
struts.

**And it drinks.** This is a supercharged 5.4 with 476 PS and you are going to use it, because using
it is the entire reason to have it. Be honest with yourself about that before you work out what it
costs to run.

**What it gives back.** It has stopped depreciating the way a modern car does, it does something every
time you use it that new cars no longer do, and there will be fewer of them in ten years than there
are now. That is not an investment and you should not call it one. It is seven hundred newton metres in complete silence, telling nobody.

## The buying guide — €24

Everything above is what the car is. This is what you check.

Six faults that belong to this engine, taken apart one by one, with
how much work each repair is and how to tell which of them you are looking at.
Twelve things that are simply twenty years old, every one
with how much work it is, what tells you about it at a viewing, and whether it has to be done now,
within a year or two, or not at all. The six places to check for corrosion — including the three panels on this car that are aluminium, which most buyers do not know are aluminium. The SBC brake system, its counter, and the warranty extension Mercedes-Benz USA announced in 2018: which cars it covers, and why it can decide whether a warning light costs you nothing or a four-figure sum. The viewing in eleven steps, including the
three moments that come only once. The sentences you say to the seller, and how to build an
offer out of what you found.

And a card you print and take with you — sixty-three lines, in the order you do them.
That comes as a separate file, because nobody wants to print a whole guide to take a few pages to a
car park.

### This is what one of the twelve looks like

**2 · Front lower control arms and the thrust arm bushings**
**Half a day** per side, plus an alignment · expensive part, easy access
The best-known W211 suspension item.
*How you notice it:* knocking or creaking over bumps, and the giveaway that is specific to this car —
**the steering twitching under gentle braking at low speed.** That symptom is this item far more often
than it is anything expensive.

No rush, but plan on it within a year or two, and sooner if the front tyres are wearing unevenly,
because then waiting costs you a set as well. Have the alignment done at the same time; without it the
job is only half finished.

### And this is how the card reads

- [ ] 1 · The cold start · *do nothing else*
- [ ] 2 · The crankshaft pulley · *thirty seconds, and almost nobody does it*
- [ ] 3 · The engine bay, engine off
- [ ] 4 · Round the outside · *corrosion and wheels*
- [ ] 5 · Inside, ignition on · *keep it short, the battery*
- [ ] 6 · The test drive · *half an hour, and it must get properly hot*

### What €24 buys, put next to what it saves

Whether you pay for an SBC unit at all can come down to **a warranty question, not the condition of the car** — and almost nobody selling one knows the answer. A crankshaft pulley left to break up has taken front covers and water pumps with it. The guide is **€24**. It will not stop any of that from being needed — but it does
tell you which of them you are looking at before you agree a price, and that is the whole of the
difference between paying for a car and paying for someone else's postponed maintenance.

### Why there are no prices in it

Because a price we cannot verify is worse than no price, and because a price would be wrong for most of
the people reading this anyway. Workshop rates across Europe differ widely, and so do parts prices. A quote from a specialist in one country tells you nothing in another.

**What does not change is how much work a job is** — that follows from what has to come off the car.
So every point in the guide says whether it is an hour or two, half a day, a day, two or three days, or a
week or more in the workshop, with a labour figure where a source gives one. And it says whether the money sits in
the part or in getting to it, which is what lets you tell a fair quote from a bad one.

If you want a figure, ask any workshop one question — *what is your hourly rate?* — and every effort
level in the guide becomes your own number, in your own currency. One question, and the answer is actually true
for you.

### How this guide was put together

Because you should know before you pay for it.

- Every fault and symptom comes from a source the guide names, the manufacturer's own documents first. The
  effort levels are our assessment, unless a source gives the hours.
- Where one complaint has more than one possible cause — and on the supercharger it has three, an order of magnitude apart — you get all of them, cheapest first.
- The effort of every job is counted item by item and checked against the list before every edition.
- It says as plainly what you can leave alone as what you have to do. Four of the
  twelve age points start from *leave it*.
