Who built it, and what they built

When the W211 went on sale in March 2002 — in Mercedes' words "the eighth generation of Mercedes-Benz's upper mid-size line since the Second World War" — it had a brake system with no hydraulic connection to the pedal in normal driving, air suspension, and a great deal of electronics. At the top of the range, the only eight-cylinder car at launch, was the E 500.

Under the bonnet is the engine that makes it worth reading about twenty years later: the M113 E50, a 4,966 cc naturally aspirated V8 with a light-alloy block, three valves and two spark plugs per cylinder, 306 PS at 5,600 rpm and 460 Nm from 2,700 to 4,250 rpm. Mercedes quotes 0–100 km/h in 6.1 seconds with the five-speed and 6.0 with the seven-speed, and an electronically limited 250 km/h, in a saloon that weighs 1,725 kg.

Two systems that were standard, and that define the car

Sensotronic Brake Control. Mercedes' own archive describes it as "the standard, electro-hydraulically controlled Sensotronic Brake Control (SBC™) braking system" — standard on every W211, and first shown in the SL a few months before. The brake pedal is a sensor; a high-pressure pump and an accumulator supply the pressure, and valves meter it to each wheel. It is clever, it was recalled twice, and Mercedes dropped it at the 2006 facelift. Every E 500 in this guide has it.

Airmatic air suspension. On most W211s it was an option. On this one it was not: "The air suspension was standard equipment on the E 500 V8 top model." So the question on an E 500 is not whether it has air suspension, but what state it is in.

The gearbox, which depends on the build date

The first E 500s had the five-speed automatic, the 722.6. From September 2003 Mercedes fitted the new seven-speed 7G-Tronic, the 722.9, as standard — Mercedes' own type data reads "as standard (until 08.2003)" for the five-speed and "as standard (from 09.2003)" for the seven. The E 500 4MATIC, which arrived in the autumn of 2003, kept the five-speed throughout. Both gearboxes are good. They are not the same gearbox, and the guide treats them separately.

How many there are, and in which bodies

Mercedes' archive lists, for the cars this guide covers:

The E 500 estate went into production in August 2003 as a 4MATIC and in September as a rear-wheel-drive car. And in June 2006 the facelift brought a 5.5-litre V8 under the same E 500 badge, conventional brakes, and — in Mercedes' words — "around 2000 components" newly developed or improved. That is a different car, and this guide stops before it.

The reputation, and why it is not the whole story

The W211 had a hard time. In 2011 Der Spiegel wrote that the W211 saloon and S211 estate "zählen zu den fehleranfälligsten Autos, die die Mercedes-Werke je verlassen haben" — are among the most fault-prone cars ever to leave the Mercedes plants — that only the later build years benefited from a quality offensive started in 2005, and it advised buyers to give the 2002 to 2006 cars a wide berth. That is every car in this guide. Mercedes' Thomas Weber told WardsAuto in 2005 that many of the ideas adopted had come from consumer electronics: "That was a mistake."

That is the history. By 2010 Auto Bild could write that it no longer received complaints about the SBC brake, and twenty years on, a car that has survived with its paperwork is a different proposition from the one in the headlines. This guide is about telling the two apart.

How the figures in this guide work

How much work each job is, not what it costs. Every item in this guide carries an effort level — an hour or two, half a day, a day, two or three days, or a week or more in the workshop — and, where it makes a difference, a line saying whether the money sits in the part or in getting to it.

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 we cannot verify is worse than no figure. If you want a figure in money, ask any workshop one question — what is your hourly rate? — and every effort level in this guide becomes your own number, in your own currency.

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

The six questions that decide whether this car is a good buy

These cars are now between twenty and twenty-four years old, and on this model the paperwork and the read-outs matter more than the paint. Six questions.

1 · What is the build date, and which gearbox and drive?

Built before September 2003, a rear-wheel-drive E 500 has the five-speed; built from September 2003, the seven-speed. A 4MATIC has the five-speed whatever the date. Those are two different gearboxes with two different sets of known faults, and the build date also tells you which of the early-production issues may apply. Ask for the VIN and have it decoded — a Mercedes specialist describes what decoding shows: "engine type, transmission, year of production, and more". So the gearbox does not depend on anybody's memory of the build month. It is a telephone question.

2 · What does the SBC service-life read-out say?

Every E 500 of these years has Sensotronic Brake Control, and the brake unit keeps a record of its own working life. Mercedes-Benz USA tells its American dealers that at routine servicing "the service life of the SBC Control Unit MUST be checked." That number, read by a workshop's diagnostic computer, is the best single indication of whether this brake system will cost you money soon or not for years — and not every workshop can read it. Who can, and what the number does and does not tell you, is in the buying guide.

3 · Does it stay level after a weekend?

Airmatic was standard on the E 500, so this applies to every car. How to see it properly — and how a seller can spoil the test without meaning to — is in the buying guide. A corner that has settled is a leak, and there is more than one place a leak can be.

4 · Is the original radiator still fitted?

On this platform the gearbox oil cooler sits inside the radiator, and when it cracks between the two chambers, coolant gets into the gearbox. A specialist who works on these cars names the radiators and the cars it is most common on. You cannot simply check the gearbox oil at a viewing, so the question is what counts as evidence instead — and that is in the buying guide.

5 · Is it dry — inside, under the seats, and in the boot?

Several of this car's control units sit in a tray under the front seats, and Mercedes has issued service information about water reaching places it should not. On this car, water is an electrical question before it is a rust question. Where it gets in, and where to put your hand at a viewing, is in the buying guide.

6 · How is the front axle — and has anything been done to it?

Der Spiegel, citing the German motoring club ADAC, reported that until 2006 undersized ball joints and poor rubber bushes wore out unusually often on both axles. On a car this heavy the front end is a real job, and it has either been done already or is still to come.

What good answers to all six look like

A build date and drivetrain you have seen for yourself; an SBC read-out with a number on it; a car that stays level; a radiator question with a good answer; a dry car; and a front axle that has either been done or is priced in.

That is a car that has left the reputation behind. The buying guide takes each of these six apart, adds what is simply twenty years old, and gives for every item 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. It ends with a card you print and take with you, with the checks in the order you do them.

Which years, which specification

2002 to 2006, M113 E50, 306 PS. That is the car this guide is about.

What comes after, and why this guide stops where it does. From the facelift, on sale from June 2006, the E 500 has the M273, a 5.5-litre V8 with 388 PS, conventional brakes, and a long list of revisions. Same badge and a similar shape; different engine, different brakes, different things to check. That is not a reason to avoid a later car. It is a reason not to buy one on the strength of a guide about this one.

Rear-wheel drive or 4MATIC. The 4MATIC came from the autumn of 2003, with a 40/60 front-to-rear split and the five-speed automatic. It adds a transfer case and front driveshafts to the list, and Mercedes issued a bulletin to replace the transfer case on affected 4MATIC cars. Neither is better; know which you are buying.

What you are not choosing between. There is no manual, no version without air suspension, and no version without SBC. On the E 500 almost everything that varies on other W211s is fixed, which makes the decision unusually simple: you are choosing a condition, a gearbox and a body, not a specification.

Beyond that, look for a car nobody has modified. Factory wheels and standard ride height. On this model an original car is more often a sign of how it was kept than of taste.

What it is worth

We are not going to give you a price list. It varies by country and by month, and it would be out of date before you used it. Here is the method instead.

On this car, price the two systems first. Two E 500s with the same mileage and the same asking price can be very different cars, and most of that difference sits in the brake unit and the air suspension — neither of which you can see. An SBC read-out with a healthy number and a car that stands level are worth more than any difference in colour or mileage.

There are three kinds of E 500 for sale.

The documented car. History, invoices, an SBC read-out, and an owner who can tell you which air strut was done and when. It costs the most to buy, and once the sums are done it is often the one that costs the least.

The tidy car with no paperwork. Looks right and drives smoothly, and the owner says it has never given trouble. On this car that sentence is compatible with a brake unit near the end of its counted life and a radiator about to damage a gearbox.

The project. A settled corner, a brake message, a gearbox that hesitates. There is a price at which that is a good car, and it is a long way below the other two.

How to compare them. Take the asking price, work through the six questions — and, in the buying guide, the faults chapter and the age list — and add what is coming in the first two years. Compare those totals, not the asking prices.

Where to look: the big classified sites in your country, the Mercedes specialists, and the auction sites. Follow the adverts for a month before you look at a car, and notice which ones stay up for weeks.

What it is actually like to own one

It is a large, quiet saloon with an engine that does its work without making a point of it. The M113 pulls from just above idle and has the unhurried quality that a big naturally aspirated eight gives a heavy car. At motorway speeds it is barely there.

The brakes may feel different. PistonHeads' guide to the E 55 of the same body notes that "some find the pedal doesn't have the feel and progression of earlier AMG models". What is not normal is a pedal that changes character during a drive, or a brake message nobody has read out.

What it costs you in attention. More than an ordinary E-Class, and in three places: the brake unit, the air suspension, and water. A battery in good health matters more on this car than on most, because a weak one produces warnings that look like something expensive. And the brakes are not a job for the garage round the corner: the system has to be deactivated before anybody opens a caliper or changes the fluid. Any workshop that has the equipment to do that can do the job — but ask before you book.

What it gives back. A 306 PS V8 in a car that seats five, carries a family's luggage, and attracts no attention whatsoever. That is not an investment, and this guide will not pretend it is. It is a great deal of car for what it now costs, provided you buy the right one.

The buying guide — €24

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

Seven faults that belong to this car, taken apart one by one, with how much work each repair is and how to tell which of them you are looking at. Twenty-one 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. Where Mercedes itself has documented water getting in, and the one corrosion check that matters more than the rest. Why you are not buying a V8 but two electronically controlled systems with a V8 attached, why a full folder without an SBC read-out is not a documented car, and why the battery ties the two together. The viewing in eleven steps, including the two 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-five 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 twenty-one looks like

13 · Brake discs and pads — and why not every garage can do them

Half a day · expensive part, easy access — and see the warning

Ordinary wear items, with an unusual procedure. Mercedes' own workshop magazine is blunt: "When servicing brake pads or rotors, or with most repairs on the brake system, the system must first be deactivated" — because of a self-test that runs after wake-up: "Pressure applied to the brake calipers during the PDC will apply the brakes, which can injure or crush body parts, or eject the caliper pistons from the cylinders if the brake pads are removed." Any workshop with the right diagnostic equipment can do it — but ask before you book.

Now when they are worn — and book it somewhere that can deactivate SBC.

And this is how the card reads

• 1 · Before anybody touches the key · you only get this once
• 2 · Door open, bonnet released
• 3 · The engine bay, cold
• 4 · The cold start · do nothing else; the seller starts it, you stand beside it, in P
• 5 · Inside
• 6 · The boot, and round the outside

What €24 buys, put next to what it saves

A brake unit at the end of its counted life is a day in the workshop, and the money is in the part. An air strut is an hour or two, and a settled corner left alone takes the compressor with it. And a cracked radiator can let coolant into the gearbox — on a car whose gearbox oil you cannot check at a viewing. 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 a warranty applies only in America — and the famous SBC warranty extension is one of them — it says so, instead of letting you price a European car on a promise that was never made to it.
• 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. Ten of the twenty-one age points start from leave it.
