Sometimes it's a pain in the butt.
I have to deal with people breaking their necks to look at the car
I was turning the corner one time and there was a group of 4 people and one of them decides to step out into the crosswalk but it wasn't his time to go. His buddy told him to watch out and he said "he can hit me, he drives a Mercedes". People expect you to tip more when you valet, or I have co-workers that always have some comment to make about finances ( "we can't all drive a Mercedes"...)
I'm not into status and gloating over what I have and material possessions. I am as humble and generous as person can get. I will say though that one of the perks of driving an expensive car is that people you give you the benefit of the doubt and I tend to get favorable treatment.
