Have to agree. Ruby Red & Ingot Silver are the best colors for the S550. What swayed my decision was that RR costs more money since it has a third layer with a tinted clear over primer over red. Always purchase the car with more layers of paint I say.Not sure if you zeroed in on color or not. Without a doubt, go for the Silver. The bodies on these cars are so sweet and the Silver has a way of accentuating the body line nuances better than any other color. The Ruby Red is also nice, but I don't know if that was discontinued or not on the 2018s.
