i currently drive a mercedes e-class. 2017. unless you are detail oriented, i think my car looks as good as an S, but too much like a C. One guy i talked to was getting rid of his s-class because it no longer has the right cachet for him. same with some beemer sedans and certainly some infiniti's. i used to pride myself on my ability to tell them all apart, just from being a car geek. now it takes too much effort.
Having said that, i did notice that the immediate way to tell a model x from the side is the two door handles being next to each other LOL
