Yes, it’s ABC equipped, though it’s the second generation ABC (also used in the 2007-2011 R230 SLs) that seems pretty reliable overall in my experience.

@@sultanqasim Thanks !

Are you looking at the 2007-2010 CL63 or the 2011-2014 CL63? The latter are quite a bit more expensive usually. The older C215 CL class was smaller/lighter, and the supercharged M113K engine was fantastic in performance and reliability. Main issue with the C215 is the first generation ABC suspension which was prone to various failures. The C216 improved the ABC reliability, though the M256 engine of the 2007-2010 cars has various known issues. The 2011-2014 CL63s with the M257 engine are the most reliable, highest performing, and most expensive of the bunch.

@@sultanqasim 11-14 is what I’m gonna get.

I like expensive German machines 😂 My next video will probably be of my W140 S class, and I plan to make some more interesting videos with my 718 Spyder. I will also be getting a 2023 Subaru BRZ later this year as a daily driver, do I’ll probably do some videos with it, and maybe a comparison with my 718 Spyder ($30k vs $130k sports car).

ABC gives better handling while remaining supple, and the only ABC repair this 15 year old car has needed in its lifetime is a $200 pulsation damper. This generation of ABC is pretty reliable as long as you’re proactive with maintenance.

I had to burn a firmware update I found on an Eastern European forum to a CD, and then followed a somewhat convoluted process to get the COMMAND system to install that update.

There’s some info in this thread, though the download was taken down which is why I had to look for the file in mercedesclub.cz (and make an account to download). www.benzworld.org/threads/known-comands-affected-by-week-1024-date-time-problem-problem-solved-iso-will-be-removed-on-02-15-2020.3011318/#post-17903584

Issues with the pneumatic seat air bladders seem really common on these. I had a local parts supplier source the air bladder + valve/sensor + internal hoses assembly for around 2/3 of the dealer cost (I paid around $1300 CAD for the part in 2019 for my CL63). Not sure who the best suppliers in your part of Europe are. It is a rather costly fix, and not mechanically critical, so I’ve just let it be on my CL550 for now, though maybe I’ll fix it some day.

@@sultanqasim Thank You very much best regards dr dragan kovacevic

Thanks. I plan to review my W140 S500 next.

Of course 😅

Is ABC available on the 2011+ CL550s in your market? As you could hear in my video, I’m fond of the handling that ABC brings. The M278 engine in the later CL550s is more reliable than the M156 in the pre-facelift CL63, but the sound and responsiveness of the M156 is great. Thanks to the torque from turbocharging, the performance of the M156 and M278 cars are pretty similar.

@@sultanqasim I'm in North America as well, as far as I know, we couldn't get the ABC because of the 4matic being standard

@@6fthondaboi In that case, between those two, my choice would be the 09-10 CL63. If the head bolts haven’t been changed, I’d keep an eye out for signs of coolant loss or oil/coolant intermixing, and consider changing the head bolts preemptively, though it is a rather labour intensive task. Also consider replacing idler pulleys and the belt tensioner preemptively if they haven’t been changed since the car was new. For the rest of the M156 issues, you can deal with them as they appear if they appear, but they’re not too bad usually. The sound and responsiveness of the M156 is awesome, and the taut handling of ABC makes the car more fun to drive through winding roads.

@@sultanqasim Are you from Israel 🇮🇱 ??

Thanks 😊 I later took the 410 North and kept going till it turns into Dufferin Road 19 passing through Boyne Valley provincial park. Could be nice to have a gathering and cruise of local CL class owners in the spring, hopefully after the Covid situation improves.

Nice, best wishes with your new car 😊. Is it 4matic or RWD? This CL550 does feel a bit more plush riding than my last CL63 in comfort mode, without any noticeable impact on handling. A 4matic (Airmatic equipped) one I drove felt even softer, though as I mentioned in the video I chose the RWD model for the sharper handling of ABC on twisty roads.

@@sultanqasim it’s the ABC RWD. As I’m a kiwi 🥝 here in NZ, I think we only got 4matic from the 2011. Cheers

@@paulburns6110 Nice 😁

Both are great. I plan to make a video of my 2007 CL550 in the spring, contrasting it with my 2012 CL63. Are you planning on a CL550 or a CL63?

@@sultanqasim I try to get a 2011’s version 😀

@@bobjensen4051 Whichever car you buy, I’d strongly encourage buying one that has been enthusiast owned and meticulously maintained by someone who can afford to maintain it. Parts for these cars are very expensive, and a lot of things can go wrong just due to their complexity. Also make sure the sunroof works properly (moves and doesn’t make any odd noises). The damaged (by previous owner) sunroof on my 2007 CL550 has been an expensive nightmare that I didn’t properly inspect when buying the car. At dealer pricing you can easily end up spending $6000 fixing a sunroof that seemed to work aside from a rattle over bumps and some odd noises while operating it.

2007-2010 are naturally aspirated, 2011-2014 are turbocharged. CL63s have more power than CL550s. M156 engines in the 2007-2010 CL63s have nice sound and performance, but some known weaknesses (like head bolt breakage). M157 and M278 engines can have some timing chain stretch related issues as they get higher in mileage, may need timing chain replacement if you hear chain rattle. The MCT transmission in the 2011-2014 CL63 shifts a bit quicker than the torque converter based transmissions, but it’s not the most graceful at low speed. I like the torque converter based transmissions better actually since they make it easier to modulate wheel torque from a standstill.

I’m a big fan of the ABC suspension, as it makes the car feel much more controlled in handling. Air suspension cars feel rather boaty in comparison.

Pretty fun on back roads actually with the ABC suspension. It doesn’t have the grip of purpose built sports cars, but the body is pretty well controlled, steering feel on the AMG models is pretty nice, and they’re pretty neutral at the limit, allowing a little oversteer if you push it. I traded this CL63 when I bought my 718 Spyder, but I missed having a CL so I bought an ABC-equipped CL550 this year. I’ve had lots of fun with my CL550, even autocrossed it - it was obviously too big and heavy a car to be fast in autocross, but it was still a lot of fun, and I thought the car did well for what it is.

I put down my deposit in April. Should get it in …?

I work in the embedded systems security field.

That could be fun. I’ll make some more videos, maybe next month. I also want to make some more videos with my Benzes.
