Upgrade to 2018 S
I have black and it's always dirty. I'm very tired of the car always looking dirty.
I do use a duster between washing. On my current S450 my only problem is brake dust on the wheels. After my last wash I tried Armor All Brake Dust Repellent, so far it is looking pretty good.
BTW: I use a rinse free wash system (Made by Optimum Car Care) which gives an excellent result.







Newer electro's etc
