I wondered about the differences and as said above would need to see side by side photos.The rear is a bit marmite, somewhat like the W205 was, but I grew to like it.
I find your comment puzzling.I have to say as much as I love the 219 I’ve never really liked any of the newer CLS’s but this Facelift looks stunning
I find your comment puzzling.
You say you do not like any CLS newer than the first generation C219, but find this model "stunning"
The current model introduced in 2018 is the C257 but the upcoming model is virtually identical on the exterior, and viewed from any other angle than head on you wouldn't know the difference....and even then you would need to know exactly what you were looking for.
Maybe it is the new blue colour that has caught your eye...as it did mine.
