Just about any Merecedes in white will look good, have yet to see one that doesn't look good.
Good chance that this will be one of the most popular colors.
Today's white paints are striking on today's heavily-styled cars. The lighter color emphasizes all of the sheet metal contours, while darker colors obscure body lines.
A car like the GLE Coupe wears an expressive body, so it's best suited to a lighter color in order to bring attention to the complexity of the design.
Other cars with simpler lines don't need a lighter color to bring out all the surface details. A darker color (like black) may fit those cars better.
