Worth Buying A 10 Year Old Mercedes? (Read this first)


Merc GL

I bought a new Mercedes about 22 years ago and I still have it. I don’t use it every day but it starts every turn of the key and still looks as good as the day I got it.

Is it worth buying a 10 year old Mercedes? A 10 year old Mercedes is capable of giving many years of great service, easily in excess of twenty years if well maintained. The reliability of Mercedes, is determined more by condition than age.

In this post you’ll learn what you can expect from a 10 year old Mercedes, the repairs that will be needed in the near future. We’ll also look at the average cost of a 10 year old Mercedes and some buying tips.

How much life is left in a 10 year old Mercedes?

Mercedes e class

Mercedes are built to last or at least the earlier models were. I bought a new c class Mercedes about the year 2000 and I still have her she was one of the first of the w0000 to roll off the assembly line.

While my car wasn’t without problems and at the time I was a little disappointed, overall I’d say it was a good car.

My C Class was the first of a new model and although I’m in the motor industry all my life I should have listened to my own advice.

I often say to those that ask me about buying a new car, don’t buy the first production year of any new model. Buy it in year two or later when all the bugs are ironed out.

So when considering a 10 year old Mercedes be mindful of the production year of your chosen model. That advice still stands.

Mechanical:

A 10 year old Mercedes will likely have a few miles on the clock, about 100 thousand miles isn’t usual. That’s the kind of mileage that initially causes you to pause when see the kind of dollars they ask for these old timers. But quality cost money and turns out quality holds its value too.

An old Merc is easily capable of giving fantastic service well into the 300 thousand mile range without major mechanical issues.

Most Merc’s are fitted with big 6 cylinder engines and that helps with durability. Mercedes do fit smaller 4 cylinder engines, but mostly in Europe. Small engines have to work harder and so wear out more quickly.

When it comes to an engine more is, well, more.

Accessorises and extra’s:

Amg seats

Mercedes are known for their luxury and so no doubt your car will have as you’d expect all the usual Mercedes refinements – Metallic paint, alloy wheels, full electric pack, parking sensors, air condition, rear camera, navigation, infotainment system, you know, the usual.

Mercedes buyers are very particular and often opt for add on’s so your car could have some very nice extra features.

Mercedes equipment is durable and at 10 years old and should all still be in great shape.

Mercedes are world leaders in car technology, they’ll typically have technology years ahead of mainstream cars. It’s possible your future 10 year old merc will have technology that hasn’t ever made made it main stream.

Even a 10 year old Mercedes scores highly in the safety tests, it’s got a ton of safety features, including auto braking and steering technology.

All Merc’s will have the usual array of goodies, but look out for the fully loaded Merc’s packing all the extras, the Moon roof, key-less entry, message seats, head-up display, all wheel drive, night vision, lane assist, blind spot detection, air-con seats, park assist etc.

These are all very nice features to have but be mindful everything comes with a price, as they age, they’ll likely cause problem and will be expensive to fix.

Body & Interior Condition:

The condition of your future Mercedes will likely be excellent. Mainly due to the quality design, build and materials, but also because Mercedes owners appreciate a quality motor.

It’s more likely than not that your future Mercedes was well cared for. Maintained at great expense and probably at a Mercedes dealership where it was loved within an inch of its life.

I would expect a long service history with lots of money spent.

Interior trim:

Most high end Merc’s are finished in the finest of Napa leather. The steering wheel and gear knob also. The trim wears really well and if cared for should look as new. Only intergalactic mileage Merc’s will show signs of a saggy drivers seat bolster and worn pedal rubbers.

Paintwork:

Mercedes paintwork and trim are top drawer. Obviously stone chips, scratches, curb rash are common to all cars, but corrosion isn’t a concern and at only 10 years old, you wouldn’t expect it to be.

10 year Old Mercedes Maintenance

Lets assume you buy that ten year old Mercedes. We’ll assume also, your new to you Merc has about 100 thousand on the clock, was well cared for and the dealer completed a full service before you took delivery.

So, what sort of maintenance are we looking at here? As a Merc owner you’ll want to keep her in the mannor upon which she’s accustomed. And that means not skimping on the care, it means doing the proper maintenance in a timely manor.

The usual maintenance items will be needed at regular intervals, of course:

  • Oil and filter
  • Air filter
  • Cabin filter
  • Fuel filter
  • Wiper blades
  • Bulbs etc

Less common maintenance items, include:

Car coolant
  • Brake fluid change every 3 years
  • Coolant replacement every 3 years
  • Coolant system flush
  • Water pump replacement (if not already replaced)
  • Brake pads replaced
  • Rotors replaced
  • Software update
  • Transmission oil and filter change
  • Struts and shocks replaced
  • Tires replaced
  • Four wheel alignment

These cars are heavy and that means they are hard on brakes, pads and rotors will wear out surprisingly quickly, so too will the tyres. Expect to replace the tyres every 10 to 12,000 miles.

Mercedes are fitted with long life plugs, they only become due a change at 100 thousand miles, and are expensive to replace. Worth checking with your dealer if he’ll change them with the pre delivery service.

Control module software upgrades are usually included in the price of the service, unless it’s part of a particular customer complaint repair procedure.

What about the unforeseen failures? Ignition system coils, cats , EGR valves, air suspension faults, wiper motor failure, engine mount premature wear.

Don’t let these put you off owning a Mercedes, I could write a list for every car ever made, it’s normal for parts to fail as the car ages.

Main Dealer Or Indy

First off I should point out the obvious, having an authorised Mercedes main dealer take care of your new wheels will be expensive relative to an independent shop.

The reason is simple, the main dealer can charge more because they have a higher level of equipment, knowledge and your paying a premium for the sizzle.

In addition the franchise network usually dictates pricing to discourage a race to the bottom by its dealers.

The independent shops will have no problem servicing your Mercedes, while these cars are unique and high tech, mechanically they are pretty conventional.

Where an Indy shop may come unstuck is when troubleshooting some of the high technology accessorises. Mercedes as per all manufacturers employ their own fault finding diagnostic equipment, (Star diagnostic). It was designed around the communication architecture of the car.

While after market non Mercedes diagnostic equipment will communicate with the system, it won’t have full functionality.

ECU

So what? Problem is, this often leads the (Mercedes inexperienced) independent tech to take a gamble at the root cause of the problem. Parts are ordered and fitted in the hope of solving the problem. Very often it doesn’t and the customer ends up footing a much larger bill.

There’s a happy middle ground, seek out and build a report with a Mercedes independent garage. These shops are often owned and staffed by very experienced and talented ex-Mercedes technicians. They offer dealer level diagnostic equipment, knowledge, skills and quality replacement parts.

Buying Advice

C class merc
  • My best advice for buying a used Mercedes, is buy from a reputable dealer (preferably a Mercedes dealer). A dealer who cares about their reputation won’t sell a bad car, or short change you on warranty issues, should they arise.
  • Know what model Mercedes you want before arriving at the dealership, that way you’ll be knowledgeable about value, accessories, service intervals, known problems, etc.
  • Model chosen, check out safecar.gov data base for recalls and known safety issues.
  • Ask the dealer if the sales car in question has had its recalls.
  • Only buy a Mercedes with a full main dealer service history.
  • Condition trumps mileage, I rather have a higher mile car if the overall condition is better.
  • Be mindful the more accessories these cars have the more likely they’ll need attention into the future when they’ll be off warranty.
  • Seek out a good Mercedes independent mechanic in your area and build a relationship. Ask at a Mercedes owners club, they usually have a ton of great information.

I wish you many years happy Mercedes ownership.
