I have a quote from MB for a 3 year 75,000 mile extended warranty of $2200 on my 2019 E450. That was about $1000 less than a third party.

I see no reason to spend more on a third party vs. a MB extended warranty.

It would cost me another $3600 USD get 2017 E400 without Auto-intelligent packge.
2017 E400 32K miles preminum package (auto-parking) vs 2018 E300 60K miles preminum + auto intelligent package.
I'm not sure if the less mileage is worth the money. It is almost half difference in KM.

There is no doubt that doing routine maintenance will not prevent parts from failing or breaking. Parts fail, break, reach their end of life -- both from use, and over time. It happens. Simple scientific fact. However, trying to answer the question -- is a Mercedes reliable enough so that an extended warranty does not make financial sense -- is not a quantifiable, answerable question. It's a simple to each their own, comfort, risk, etc. It's nothing more than risk management. As far as "the electronics are either good or bad: they either break in the first six months or last forever." -- no disrespect, while that may be your personal experience, there is no scientific data or proof that will back that up. If it's your experience it's a small sampling. My experience is the opposite, and is also the same; meaningless.

While I agree with you -- if you intend to keep your car beyond 75,000 miles, then an extended warranty might make financial sense -- I can hear people opposing and arguing that all day long. You and I simply disagree with them. I absolutely accept that most people who don't buy the extended warranty are happy with their decision -- and they are probably has happy with their decision as I am with mine to buy it. LOL.

Actually it is quite quantifiable: You take the cost of the extended warranty, plus tax and use of money: that is a fixed amount. Then you take a broad sampling of owners and see what their cost beyond routine maintenance are: You compare the two and you have your answer.

As I posted, I started a thread several weeks ago asking for owners with extended warranties whether it made financial sense or not. While there have been over 275 views, to date there have been only two replies - (just checked you were not one of the two). If people who bought the extended warranty thought it was a good buy they would have posted.

I think the fair conclusion is that the extended warranty has not been bought by most and their are quite satisfied with their decision.

No disrespect taken. I think we have all owned a TV, Computer and even a car, where in the first six months the electronics continue to go wrong and/or break. I think we all call this a "lemon". On the other hand all of us have products that work from day one and never seem to break. The electronics in a car are no different.

To quantify, what did you pay for your extended warranty with tax, and so far what issues have been taken care of under the extended warranty?

First, that's not accurate. Second, it's a fallacious exercise. Third, you haven't quantified the real probability. A broad sampling doesn't do it. Risk management is a science. You are trying to exponentially oversimplifying. In risk management, there is a "point of diminishing return" on cost/premium dollars. At that point, you begin to self-insurance" and this is very quantifiable.

However, anyone can go through this exercise and make their decision if they so choose.

The most important question posed which you did not answer:

What did the extended warranty cost and have you used it? Or to date, has it been a waste of money?

Whether 2 or 200 answered, they are incidental and circumstantial. Not authoritative. Flip a coin 99 times and it comes up heads. Flip it one more time, the odds are still 50/50 on the 100th flip. The first 99 mean nothing. It's really a fallacious argument, except in hindsight. Personally, I wouldn't argue with anyone who makes either decision. All good points though -- thanks!

Thanks:

I notice a reluctance on your part to disclose:

• the cost of your extended warranty; and
• whether you have used it.

Real life experience would help the rest of us, at least for me it would, as to whether the extended warranty in general and in particular the one you bought, makes financial sense. While your experience may be a "one off", it is still better than guessing and pure speculation.

Hope you feel comfortable answering.

I bought the MB warranty -- NOT a third party -- and I think I paid about $2000 (for the three years, to adjunct what was left on the original and the CPO). I obviously haven't had to use it as I still have the original and the CPO. All repairs to date have been covered by one of those two, a service recall, or simply not covered by anything at all! LOL.

As I posted, I only considered extended warranty from MB, not a third party. I was quoted $2200 + tax, 3 years 75,000 miles, from two MB dealers for my 2019 E450.

I have owned my car from day one and as I posted the only repair was a replacement of the intelligent lighting switch at about 2000 miles. Otherwise trouble free.

Unless you pulled the VIN before purchase and checked what if any work was done on your CPO, you are "flying blind" as to what other work and/or problems your car may have had. Your car may have been trouble free or not. Not knowing, an extended warranty might make sense.

Your situation is different than most others, who are the original owners, as I am, and are approaching the end of the warranty period and must decided whether or not an extended warranty makes financial sense.

When my car came off of lease I decided to buy it. It has been trouble free. If it was not, I would not have bought it, it being a "lemon".

I bought mine used and CPO. The dealer had ALL service records, very detailed, and the previous owner did a great job with service, mandatory, and optional. They sold the car new, serviced it, and took it back from the guy. I'd buy another car from this guy again! LOL. I only bought the warranty because that's me, LOL. I drive, add gas, and bring the car for service. That's it. Period. Plus, as well as it was maintained, like you said, who knows. I can't control the cards I get, but I am in control of how I play the hand, LOL.

When I got new cars from MB, and I planned on keeping it more than 5 years, I bought the extended warranty. It's transferrable and it's a selling point. Who knows, maybe it means nothing. When I leased cars from MB, I didn't buy it. Why would I, LOL. Like I said, I wouldn't argue with the person who does buy it, or the person who doesn't. Thanks.

I bought my 2019 E300 4matic in April not knowing about the piston issue (my stupidity for not checking) but I did cough up the cash for a third party warranty (even though it had only 19,000 miles on it Mercedes wouldn’t do extended warranty or CPO because of the age. The warranty will cover repair expenses up to the price I paid for the car. After reading some of the posts about piston #1 in the M274 engine I’m glad I did!

I bought a new '18 E300 in July 2017 and other than a couple of issues when delivered (weak door hinges replaced, ...) I have done nothing more than scheduled maintenance. The car is a couple weeks short of 6 years old. I expect this car's EOL will match my own EOL.

As a data point, when my 2018 E400 was end of lease, I bought it out. At that time I paid ~3350 for the 3/100 extended warranty. I never used it. What I paid for was peace of mind. Extended warranties exist for a reason, they make the issuer a lot of money. In general, cars are built so well now they know you won't likely need the warranty. Simple numbers game. For that one out of a hundred person that bought the warranty and their engine blew, money well spent!

On your sample size of one, you are correct. Furthermore you bought the most reliable E-Class version, a M276-engined model. The four banger E300 and V8 E550/E63 have far more problems and far more expensive problems. Your experience is unsurprising, and it has turned out well for you so far.

That is a great reason as well.

For sure, I read about the engines before I purchased. Now I have an EQ, God help me

The M276 V6 engine also have some issues such as High pressure fuel pump, tendency for Carbon build-up, Timing chain tensioner and Plugs & coils fouling up. I would say both the M274 I4 engine and M276 engines are above average in reliability and both engines are extremely fuel efficient.

I guess the M256 was never introduced without the 48V mild hybrid, such a shame because the M256 might be able to compete if not reliability then at least in the fuel efficient department (sure the M256 with the 48V mild hybrid is more fuel efficient than M276 but it is not a fair comparison with the 48V mild hybrid system keeping the engine off when coasting for example and off when stopped if auto/start stop is on)
The smoothness of inline-6s is a huge bonus as well.

The lastest JD Power reliability report shows Mercedes near bottom, reliability has been on a downward trend for the last 5 to 6 years.

it is not the same company that I invested in in 1980.

The only E class that I had reliability issues with was a 2003 E500. It had standard air suspension that was very expensive to repair. Even so it lasted 5 years. My record was a 1977 300D (5 cyl) purchased new and driven about 50,000 miles per year for over 14 years without any repairs other than normal maintenance items - battery, brakes, tires, lubrication. It was a commuter driven between Clearwater, Ft. Meyers and return 5 days per week. Overall the E class cars are the most reliable Mercedes cars built thanks to their taxicab heritage.

I was going for a million miles, but my client base expanded and I switched to air travel.

I see....
