They are really confused and in disbelief when I tell them that no, it was intentional.

The advantage (other than me just liking fancier colors and disliking the prevalence of grey in cars) is that I can find my car in even the largest parking lot from very far away, and that people instantly recognize me as it's seemingly the only yellow Mercedes-Benz in the town where I live (~100.000 inhabitants) ;-)

Recently I overheard two kids (a boy and a girl, around 7 or so) who drove by my car on bicycles, loudly proclaiming "I would never drive a yellow Mercedes". I wanted to ask them why, but they were too quick (and probably embarassed that I overheard them). I would really love to know if it was their own (genuuine) dislike of the color yellow, or if it was something they acquired from their parents or something like that.
