Nope. Gold vinyl still doesn’t look good. Mercedes gets a pass here though because the color is appropriate for the Cannes film festival. The fleet of gilded limos and SUVs are intended as a tribute to the 65th annual Palme d’or, the highest award available at famous festival.
So no, this isn’t just Mercedes giving a nod to the more ostentatious leanings of their owners. If anything this is just Mercedes’ way of being even more classy than normal. Does it look good? Well no, but sometimes it’s fashionable to be ugly.
