Yellow is always a hit or miss color when it comes to German cars. Some cars it looks great on like a Porsche 930 or a Volkswagen GTI 20th Anniversary Edition. Other cars, maybe not so much. When it comes to yellow Mercedes-Benz, there aren’t a whole lot of them out there. This was a hot color in the 1960s and 1970s, but outside of the first-generation SLK and the new AMG GT, you won’t find many painted in this bright shade. When you do, it is literally just a handful of them and they were probably painted that way by special request. Today car, the king R129 SL600, is painted in the factory Yellowstone 685. At least that is how it sits now. Let me explain.
