Is Mercedes an "old people's car"?

I bought a 2014 E350 4matic last week and I love everything about this car. I'm 23 and some of my friends have remarked that I went straight to old mans car and should have gotten something smaller like a BMW 3 series.Curious as to what your thoughts are on this. via /r/cars http://ift.tt/2tKvkXO
