And what do you think was overdone completely for years before people began putting black wheels on white cars?...Silver!
If the opening question applies only to white cars, take a good look at all plastic inserts on the polo 6R, everything is matte black apart from the 2 door pillars. If you are truly interested in complimenting a white polo with a black wheel, it is matte black or nothing.
