Color is everything. Kind of a broad statement, I know, but when it comes to classic Mercedes-Benz, it is pretty important. Light Ivory, Astral Silver, or Pastel Beige? Okay colors, but no one is clamoring over them. Henna Red, Mimosa Yellow, or today’s car, China Blue? Now people are excited. In all seriousness, I do see a fair amount of price different between two comparable cars with one painted something bright, with the other a little more drab. It just so happens that this 1981 300SD up for sale in Atlanta is one of the few to be painted in the aforementioned China Blue. So that begs the question, how much of a premium will this bring?
