I owned my 2017 M3 with SS for over 5 years now, and with two kids (5 year old and 2 year old). I drive them daily to preschool every day and they eat and drink in the car. The leather is completely clean and almost like new. Whenever it's dirty I just wipe it with a wet microfiber towel and it comes right off. Maintenance is no different than black leather, and in a way SS leather is cleaner because whenever it's dirty you'd notice it right away and clean it. Whereas with black leather you'd never notice it's dirty so it's not cleaned, and even though it doesn't look dirty, it actually is.
