Have you looked at designo graphite? Is it pretty much same as palladium silver?

 

I didn't see any designo paint options at the time I placed the order, and wasn't enough time to change it before production.

 

 

Owned a 2011 G55 in Matte black (Designo Magno Night) and drove it 70,000 miles until 2015. Washed it once a week in regular brush car wash, never removed any bird poop. Just asked the car wash attendant to turn off all the waxes. It was slightly more shiny when I turned it in but still beautiful black matte. MB matte paints have a thicker double matte clear coat layer and are therefore less likely to scratch and chip! Dealer was amazed how well it looked when I turned it in and was even more amazed when I told him how careless I was with the paint. Enjoy your matte cars, no extra care is needed! the paint is made to endure snow and acid rain for at least 10 years. Do you really think it matters how you wash it? Just don't scratch it because matching the color can be difficult by the body shop but doable with some trial and error and matching the black matte is easier than the silver matte just because there is less light reflection.
