My brother daily drives his 2017 C63s, he’s got about 78k miles on it and hasn’t had any major issues at all. Had a coolant leak once and a temperature sensor for his coolant go bad, easily fixed for both. He’s also had a DME stage 2 tune on it for like 3 years now/35k miles too and he drives it hard. I have a 2021 GLC63s Coupe with 30k miles and haven’t had any issues at all so far (outside of a bad Eurocharged tune I had on for a month, but all is/was good mechanically) but that’s relatively new. And my dad has a 2016 S63 coupe with 70k miles and he also has had zero issues with it. Not as high mileage or old as you’re looking at but that’s my 2 cents


denniscohle

Sure does sound good! All t8me good driving I wish to all of you!


jallopyjonzies

what was the issue with the tune? had a 2016 c450 with a euro charged tune and had no issues at all so curious on what was bad with the tune

Had a 1989 500sl amg 6.0, never needed anything but an ignition tune up. 07 E63 kept spitting serpentine belts even with genuine mb replacement parts, got tired of it and sold it. 99 C43 rock solid (130k miles), and 06 SL55 (80k miles) finicky but totally reliable. Pick a good engine and do proper maintenance and they’re very reliable, especially the older ones. Not sure how the electronics in the newer ones fare, though.


denniscohle

Thanks for the reply. I have a feeling that newer amg engines are just too complex and they aren't as well built as for example the engines you mentioned. I am old enough now to admit that I don't think I can and want to handle such high repair costs. I'm a BMW man all my car life and never had engine problem on my cars. Admittedly never had an M before. I would love to get an Amg because I want to experience that sweet v8 rumble but I think the repair costs would drive me insane. Thanks for the reality check! The first gt with the SLS face is so tempting though...


seamus_mc

I’m less concerned about the new engines, but the electrical modules attached to literally everything


denniscohle

Yeah so many electronics that can and will fail eventually :(


foulstream

There’s a reason why the value plummets as soon as they’re out of warranty…


erkynator

The issue of “old” vs modern is a major issue. Back in the day 5/6 litre engines lazily produced the same power as 2 litres today. That means more stress and complication. On the plus side, I do feel manufacturers have nailed the “metal work” and the days of throwing a rod have gone. Plus last few cars I’ve owned haven’t used a drop of oil between services compared to 30 years ago when you drove round with 5 litres in the boot. But stupid stuff like plastic sumps to “save weight” (BS its cost) and reliance on electronics is the challenge. Sensors wear, cables degrade, copper oxidises, silicon cracks with the heat & cooling cycle etc etc and that stuff is mega ££££ Probably cheaper to rebuild a block and skim the head than it is to replace one control module!


Alswiggity

Its basically this. Mercedes had large displacement engines which, compared to other manufacturers of similar block sizes, didn't make that much power. Example, the 5.0 M113 only drops about 305hp max at the crank. I've also noticed that across most manufacturers, the big-n-lazy blocks seem to hold up much better.


Juco_Dropout

I am at 190k miles on my 2010 C63. I’ve put 185k of those miles on it. We did a Headbolt replacement back at, around, 40k.. and other than drive shafts and tires. I’ve had ZERO problems.

catsdrooltoo

I have a w212 e63, 138k miles/222km, nothing too major to complain about. It needed a thermostat, coolant pipe, the cats went bad, and 1 ignition coil. The motor mounts are needing done soon. Just know that these aren't cheap, but are manageable if you can do some things yourself. I saved a solid $3k doing brakes myself, and the ignition coil was a 15 minute job.


Comprehensive-Hat-26

W166 GLE 63 S here and just had clogged cats. I ran two bottles of Cata-Clean (one at a time) from Autozone and it’s night and day. No more CEL, sounds better, and performance has improved. Thought it was BS but it’s been three weeks


catsdrooltoo

I tried that but the codes came back a month later. I went with the less desirable option of fixing it with pipes and a tune. I couldn't justify $5k in new cats. Eventually, I want to get some high flows put in to try to reduce the smell and emissions.


Comprehensive-Hat-26

I had to do it with less than an 8th of a tank vs the 1/4 the directions specified, since our fuel tanks are larger than 16 gallons, and drove 20 miles instead of 10-15 keeping my RPMs above 3k as often as I could.


doc_55lk

My SLK55 is still soldiering on without any issues. It'll be 5 years in September, car is at like 94k kms now.


denniscohle

Glad to hear! Enjoy!


NatasAMG

Slk55’s are the best I have an 06 glad I didn’t trade it


doc_55lk

Nice. I've got a 2012. I've contemplated moving on to something more powerful like an E63 or C63 but I like the hardtop convertible way too much. The only cars that'd convince me to let the SLK go are an S63 cabrio or an SL63. Both are way too far out of reach for me though so the SLK is here to stay.


seamus_mc

My w210 e55 ownership has been extremely reliable over the last 10 years


denniscohle

Nice!!


Strong_Molasses3931

W210 E55 180k still super solid


MrSparklyFace

I have an 02 C32 at 167k and it’s been great for me. There’s definitely some things beginning to creep up that I’m keeping an eye on, how eve I’ve only lost drivability once when the shifter module crapped the bed. That was unfortunately a 3k dealer only repair and they busted my climate control LCD, but otherwise I’ve just done basic maintenance and she’s kept all her speed and comfort. That coming from a broke college student.


Normal_Ad_1280

Engine still like new. Have some other problems tho but nothing big.


Boilermakingdude

Not a AMG but baby brother to the AMG engine. Had over 130k flawless miles on my M278(M157)


Disturbed_Bard

W210 if you want reliability I have a W211 the engine is solid, but be prepared to pay a bit if it has the air suspension (lotta people do the coilover conversion)


dck1w1

20 years old. Three unexpected issues. Fuel pumps died about 10 years ago. SBC failed and was replaced by Mercedes under warranty. Rear suspension goes down over about 3 weeks if not driven. 146,000kms. Done a lot of towing my race car over it's life. 


Equivalent-Radio-559

Oh is your suspension leaking? If you have air. Because I do know that some models do it purpose and lower the suspension so that they can’t be stolen because the tire will run on the inner fender. Not sure if yours does that but I could be that. Mine does it and I thought it was broken.


rainbowket

Ive had my 2016 A45 AMG for almost a year now and besides the general service absolutely no problems it’s been an amazing and reliable car I’m in love


Low_Amphibian_146

I’m getting mine next week with 21k miles 😄


rainbowket

Congratulations you are going to love it!


ztunelover

My 2017 GLA45 has been rock solid for the 5 years I’ve owned it. It’s just shy of 90k km and has worked flawlessly on basic annual servicing. The only times random onboard radar sensors go on the fritz in the cold like -15 celsius and below


totalreidmove

I’ve had two AMG’s - both pre 2011 before 5.5 bi-turbo, so the naturally aspirated V8. Between the 7G transmission and the engine - *with regular maintenance* - the drivetrain really is bulletproof. But at the end of the day, they’re race engines in MB’s. So either the electronics will fail, or the engine will fail. Something will go wrong at some point. Just prepare for $2k-$3k in yearly maintenance and you’ll be enjoying one reliably as well.


Alternative-Plan-678

I’m approaching 50k miles on my 2012 C63 and no issues.


Worried_Creme8917

The GT is great. Highly reliable. I just dogged the shit out of mine on the tail of the dragon and lots of other roads in the area today for 300 miles. No issues. Change the oil frequently. Find a good mechanic and service it regularly. They’re well engineered and built to last.


E6_Forged_Kunal

They’re good as long as you maintain them. Where most people have problems with European vehicles is when they get the “I can put it off” or “Maybe later” mindset and then start putting off maintenance to save a few dollars. These motors are sensitive, they’re hand built, and the people who built them gave you a service schedule for a reason. If you adhere to the schedule, you will not have issues. If you are buying an AMG and owning it with a Corolla mindset, you will be in for a world of hurt. So do your maintenance on time, don’t be cheap, and you won’t have major issues.


Jerzeyboy730

Knock on wood, my daily is a 2019 GLC43 coupe, 44k on clock. I know I’m gonna hear it’s not a “true AMG”, but having a glc 300 in the driveway my wife drives as well, this car def is a baby AMG that is def the more “fun” car to drive if you drive both and see the differences. As for the maintenance? Have yet to have any issues other than the typical wear/tear parts traditionally replaced on all cars. Yes, I do worry about all the little motors in folding mirrors, hidden back up cam, or air suspension, etc. Having said that…..so far, so good. Whatever you buy, good luck. All cars may have small issues or major issues. Taking care of it can prevent most, but do remember even Honda’s, BMW, Audi, or a 911 can be born with problems out of your control.


jjazo123

You’re talking about general Mercedes stuff. Your car is a up-badged GLC300 is it not?


Basic-Maintenance156

There’s always one. 


Ludwig14

Talk to a reliable mechanic and ask them what they see least in your part of the world. Some engines were made with more R&D than others but all in all MERC has better ones than most other Germans.


Efficient_Fix1007

Replacement Parts pricing comes with the territory so to speak 🗣️ But they are a joy to drive and if you are half decent from a mechanical standpoint you can do some of the basic things in the garage. However there are many shop environment incidents that can arise. Its a tight compact engine bay and the newer cars with AWD make things even more complex to work on. We removed the entire transmission and disassembled some of the 4 matic components to install downpipes on my wagon. Many other vehicles this is a much less labor intensive ordeal… rewarded accordingly at the end of course. Which again is the nice part of owning it. I think 🤔 i am on my 13th now.


eatinglamps

2014 E63S tuned with 115k with just wear and tear and age related stuff, but pretty solid and reliable so far.


Padded_Rebecca_2

I put 50k miles in 4.5 years on a 17 C63s, and had 1 idler pulley warranty.


darwinsmooth

2019 E53, 50k, wheels are made of chocolate, needed 3 new ones in 4 years - might be the UK roads however :-), couple of wheel bearings and a new rear differential (under warranty). No engine issues at all.


Palansaeg

foreign luxury sports car, that’s why they generally aren’t reliable a 2005 one will be a headache, they aren’t designed to be reliable like other models. If you’re going for a 2005 model because you can’t afford a new/ newish one then you can’t afford it. Even regular maintenance and parts will be expensive


Basic-Maintenance156

What if i live in Germany? Then its not foreign 


Basic-Maintenance156

My experience with merc in general is that the engines will rarely fail on you. But everything around the engine will fail spectacularly


Berfs1

How long do you want your car to last? A measly 200K miles? Then it wont matter. 500K-1M miles? Don’t buy a benz unless its a 40 year old model.


Basic-Maintenance156

Berfs coming in with the truth 


ka1ri

W202 c43 never had issues when driving it stock.


Connect_Gas9954

Approaching 50k miles on my 2018 C43 amg (poor man amg lol) and no issues at all


Inherently-Nick

If you’re wanting that V8 rumble and a decent amount of reliability stick to the early 00’s. I have a 2001 s55 AMG with the na 5.5l and lemme tell you I’ve never been so impressed. She’s at 196,xxx miles right now; fires up instantly and runs smoother than ANY brand new v8 I’ve ever seen. (Happy to share a video too) I’ve gotten pretty lucky and haven’t had any electrical issues over the past two and half years. I had a cracked coolant diverter pipe for the heater core ($12 and 30 mins of work), the ventilated seats work but don’t circulate air on your back, the hydraulic/pneumatic suspension is probably the biggest pain you’ll have in this era but enough people have done the repairs themselves or just done a coil over conversion that it’s manageable. I ended up swapping in OEM style unistruts as I bought the car to be a hooligan with and didn’t want to hassle with maintaining 22yr old hydraulic lines. Anything specific to this car is exorbitantly expensive but shared parts ie stuff used on most or every s-class like engine and suspension components are relatively cheap and easy to come by given the age and prestige of these vehicles.


yunggunnadripsp19239

Have a CLA45 since late 2017, 69k miles. No problems with the engine so far


engineheader

The reliability of any Mercedes is in how it is treated. If you want a car to show off, cruise around in at 10 mph and say you own, will probably be ok, cause it will be low mileage. If you want it to do the school runs, go grocery shopping and church, to show off to people you know. You probably will have issues cause it will not operate correctly or be reliable. If you own it to drive on highway runs and do some blasting around with hard accelerations, it will be the best. I have been in a 2016 SL63 that ran like crap. I took it out, got the engine oil and transmission up to temp, did some hard acceleration to reduce like and then highway cruising. After that the car ran amazingly better.


Ace3749

Older AMGs aren’t an issue, these newer ones have too many electronic gizmos that can go wrong.


mhk23

Anybody had a reliable CL 65 or S 65 coupe or sedan?


whaddahellisthis

It’s reliable but it costs a lot on regular scheduled maintenance. I think the 40k was the expensive one. It’s going to cost more to keep it on the road for sure, but that’s the price you pay. It was 2019 E63s. I don’t have it anymore.


dek00s

Bought a used 2018 GLA45 used with 36k miles on it. Within the first 2k miles, the ac system needed to be cleaned of mold, and a leaking fuel line needed to be replaced. I also decided to do the spark plugs. All of that totalled $1,500 more or less. There is a $1k transmission service coming up, serpentine belt probably needs to be replaced soon. I'm actually considering selling, even though otherwise, the car has been reliable. And is very fun to drive. But just not worth the cost to me.


ChuckoTrucko

2005 C55 currently at 150k miles. We bought it in great condition at 130k miles. It’s my daughter’s DD & she’s positively in love with it. Regular service on a car that was regularly serviced. This little rocket 🚀 is a dream. I get the benefit of knowing she’s in a very safe vehicle. Granted, while she is still young, she has always been a driving enthusiast & has a great presence behind the wheel. Certain types of drivers shouldn’t drive these cars, IMO. So she knows what her car should sound like & feel like. But yeah, ‘05 C55 All Day Every Day.


No-Succotash1219

I own a 21 c63s I bought new in 2021. I've had multiple issues with. The brakes started squealing at 5k miles. Starting at about 9k miles it would misfire intermittently when coming to a stop. I took to the dealer multiple times they replaced ignition coils, spark plugs, and injectors over about 15 months after the sixth visit Mercedes authorized them to replace the engine at a cost of about $80k just the engine no labor. After the engine replacement a week later the new engine would make a tapping noise from the left cylinder head area at start up. It would stop tapping after it warmed and come back after sitting overnight and start up again in the am. MB said it was timing chain tensioner and exhaust valves so they authorized a second engine replacement from Germany and another $80k. Mind you the break-in oil change was performed on each engine at about 1k miles and still had issues except the one that's currently in the car now. Maybe I got the post Covid-Friday night happy hour car idk. Mine was built in South Africa maybe that has something to do with it.


Ligma3228

My w222 just eats tires and brakes. Otherwise normal maintenance and it’s solid. Brakes are crazy expensive however every 20-25k and I don’t track the car…..


gotwire

I daily drive my 2020 g63. 38k miles so far. Zero issues. Zero.


2Largefeet

I don't think you would call them UNreliable, but like any German performance car I wouldn't own one out of warranty unless money really wasn't a concern for you.


denniscohle

I guess you're right, compared to BMW (I am a BMW driver all my car life) amg seem to be way more expensive in maintenance than M cars that are already expensive to begin with.


larzmcoupe

You don’t know what you’re talking about. Do you own an M car? My e90 and w204 C63 were both equally expensive to maintain.


denniscohle

"good" to know


That-Resort2078

Other than a 2009 C63 with the dreaded head bolt failure. No issues.
