How's your W215 CL55/65 holding up?
Is it true that driving it often makes it less susceptible to breakdowns or vice versa putting on less miles?
What about city driving versus highway driving it would seem I was driving would make the car more reliable less prone to different car components breaking.
I'm talking about ABC suspension, motor, electronics, etc.




Extremely poor.

No.

I did a combination of both and it broke on the hwy and it broke in town.

ABC is the worst thing about the car. Motor is great. Electronics are average.
I won't pretend to know why. Maybe it stops the seals drying out, maybe it stops joints seizing, maybe it keeps the fluids circulating, may it keeps the battery charged. I think the best explanation is that it helps to keep the car warm and dry, and avoid condensation getting everywhere.

besides the normal maintenance plugs, random gaskets, brakes, and the MB recommend Tranny service. i haven't had any problems thank who ever up their lol. granted just a week ago the gear selector broke, ****ing $500 later to install a $100 part. but ABC been great, the pump was done before i bought so that was nice.
Repair the drivers door wiring
Replaced warped rear rotors that were new when I got the car
Replaced the passenger seat occupancy sensor
Replaced the serpentine belt and an idler pulley when the pulley failed
Replaced one of the horns
Replaced the battery
I still need to figure out how to aim the drivers headlight which has a broken adjuster
and still need to replace the air bag control module.
When I got he car, one coil had already been replaced. I drove my car with an ECU tune for about 6 months and over 3,000 miles on the original drivers side coil. I replaced that original coil before my first track day even though it was working fine because I figured it would fail there if I didn't.
I also drive mine almost every day, even in winter. My car has been driven in sub zero weather a lot last winter, blizzards, sloppy melting slush/ice, rain, over 60 passes at the track this summer, etc. It does get to sleep in my heated garage every night though.
Reliable, uh.... no. The car had a lot of repairs before I got it so IMO that is a lot of stuff to go wrong with a car in under 50,000 miles. Heck, it has had a lot more repairs than I'd expect in a modern car at 150,000 miles. But I love driving it so..... time to get off the internet and go drive to another city for a friends birthday party now.

Went to leave last night but it was freezing rain so I let the car warm up for a while. When I headed out to get in it I smelled something burning. Got in the car and ABC warning was on. Pulled it in the garage and shut it off and it left a big puddle of hydraulic fluid on the driveway and a trail of it going in to the garage.

I see you're quite modded on your CL, might as well do a coil-over conversion now with your ABC issue

Plus normal maintenance and tires... All in all for a 9 year old car I don't consider this unreliable... The repair costs are crazy but I knew that going in. I love this car and have no idea what I would/could get to replace it when the time comes.
When I first got the car I put a lot of work into it:
Replaced 2 struts and boots
02 sensor
spark plugs
brakes
Battery
Fix trunk (wouldn't open remotely)
Service at Dealership
After the above, I made a lot of performance and cosmetic changes. I only put about 5000 miles on the car since I bought it and the only problem I have had since my initial repairs has been the battery because I don't drive that often. I also have brought in for regular servicing but no problems.
