To each their own. Different people have different needs.
I love my Benz - 12 y/o, looking brand new, extremely comfortable, with no rattles to speak of and a power plant that would dump heads into the back seat if not for the head rests. (4Matic helps with that. She just jumps off the line.)
It's all good, if you have what you like.
The next birthday is 60. Maybe I'll get that AMG S63 for myself.
But I doubt it.
