No doubt, a used Mercedes does not guarantee years and years of perfect rides and tours.

You take a chance when you buy a used car that has more than 100,000 miles. Moreover, Mercedes models are luxury cars and can cost more for maintenance and repair. 

Most Used luxe cars( More than 100k Miles) are Cheap to buy but not cheap to own

Cheap to purchase, but expensive to keep up and maintain.

A car that originally cost $100,000.00 and can now be purchased for approximately $35,000.00 after only 3 years has got to be enticing, right? 

Of course, it is, and you really get a lot of cars for the price when you purchase this one. 

The problem is that it does not matter how much you paid for it used; even if you maintain it and insure it like a luxury car, you will still have to pay luxury car prices. 

Actually, used cars cost more to maintain in some ways because you no longer have the protection and peace of mind that comes with that all-important manufacturer warranty, and the service for 48 months is probably the most expensive one of them all.

Also, There is more that can go wrong with all its advanced features and technology.

Should I buy a Mercedes with over 100 000 miles?

Is it wise? No. They’re expensive to maintain. You should never finance a high-mileage Benz, BMW or any other luxury car. 

People usually trade in high-mileage vehicles that they have owned for 12 months or less.

Between the monthly payments, insurance and maintenance /servicing costs it’s just way too much spending than they expected.

So, Whatever you expect to pay for the used Benz, double it (maybe even triple it) and decide if you can afford that.

Despite the expectations of reliability that you may have for a particular manufacturer or model, the most important factor in the reliability of a high mileage auto is its maintenance history

The importance of maintenance is proportional to the miles on the car. It’s as simple!!

In the end, there is always a bit of a gamble with a used car as you probably do not have a warranty. 

You might get lucky, but the more time and miles go by, the luckier you will need to be to avoid high costs.

Mercedes-Benz Warranty-Out Of Warranty Costs

Like many luxury cars, Mercedes-Benz cars feature a 4-year or 50,000-mile warranty. 

If your car develops an unusual problem within this period, you can have a repair or replacement done.

Nevertheless, you should still expect to pay for having minor repairs done like tires, brake pads, air filters, fuel filters, and that type of thing.

If you buy a luxury automobile, even if it’s an inexpensive used one, you’ll still have to pay a lot of money in maintenance and repairs. 

Buying a pre-owned Mercedes, even if it’s still under warranty, is a hazardous move because not everything that may go wrong will be covered.

Purchasing a Mercedes after the warranty has ended is much riskier because the owner is responsible for paying for any repairs that are necessary.

Mercedes-Benz common problems 100,000 miles ahead

A handful of Mercedes-Benz car models are beginning to run into problems before they reach 100,000 miles. So, find out when your car is going to experience problems before you buy your car. 

Some of the usual problems before your car hits 100,000 miles are here:

Spark plug failure

Most Mercedes-Benz car models develop problems with spark plug about 100 kilometres; that is, before or after 100 000 miles. Pumping plugs help the air/fuel mixture to ignite. 

Your car, however, takes several miles to wear off this electric device.

Not only Mercedes-Benz but all cars are involved in the spark plug problem. 

A poor or unsuccessful jet plug may lead to problems such as motor fires, poor gas flow, difficult starts and rough idling.

It’s not difficult to replace spark plugs and even a DIY enthusiast can do it.

This can lead to problems like fuel efficiency, starting difficulty, failing emission tests, black smoke from the tailpipes, and more. 

To prevent further problems with your car, you should replace the catalytic converter. Note that the new catalytic converter price varies between models.

Failure of Ignition.

In most Mercedes-Benz models, a typical problem is ignition failure before hitting 100,000 miles.

After 75,000 miles, most models of Mercedes-Benz develop an inflammatory fault.

In the engine combustion chamber, an electric spark must be formed at a precise time, helping to ignite the air/fuel combustion.

Common Issues with Mercedes-Benz after 100,000 miles

Here are the most problems for the Mercedes-Benz model car.

After 100.000 miles, many Mercedes Benz cars begin to develop problems. 

Here are some of the issues you should expect to face when you reach over 100 kilometres:

Suspension and steering system failure

Other problems that all owners of the Mercedes car should be prepared to address when they cover 100km are the suspension and steering system. 

The suspension system consists of springs, wheels, pneumatic air, connections, shock absorbers, arms, tie rods and ball joints.

Some Mercedes Benz Car  models have problems even before 100k miles, such as control arm bushes, tie rods, sway bar links and ball joints.

When your car reaches 100k miles, always check these parts.

With your car ageing and travelling miles, expect rust to be found in many parts.

Although one of the best transmission systems available on the market, Mercedes-Benz is also one of its weakest components. 

A 13 pin connector and valve that can lead to problems after hitting 100 miles are provided in the 5-speed automatic transmission.

The connector may begin to leak transmission fluid after 100 kilometres, while the valve body could cause a bad shift.
