Reliability
Mine, a 19, had problems. Not engine related though, other than the usual AMG stutter, weird downshifts when coming to a stop in S+, etc.
Lots of creaks, rattles, etc. though!
I also had the 5k 3D burm. sound system, the amp had to be replaced after a few thousand miles.
I could go on and on. I currently have a 2020 GLC 63. Liking it better than the E63s so far. Other than the power deficit.




for sure, it’s a hit and miss for some owners.
