What’s it like living with a true luxury car?

As I have another similar post going on about sports cars, I’ll provide a tight definition.

In: S class (ideally a high spec one not a basic diesel, 7 series, Ghost, Flying Spur, A8L (ideally a top end one). Must be less than 3 years old unless it has reached classic status. I’ll allow full fat Range Rovers ideally top spec. G63. Designed for rear passenger comfort as the top priority but there are some exceptions.

Out: your 5th hand 545i with 200k on the clock and a no more than a tenner of fuel in the tank. Range Rover Sport. X5. G500. Sports cars or supercars or M5s are excluded.

What’s it like to live with? Roughly where do you live (to get a sense of the environment). Is it your daily? What are the pros and cons? Is it much harder to live with than say a C class? Are they worth it? What do regular people not understand or know about owning a luxury car.
