It also means that when Mercedes decides it's not cost-effective to maintain these subscription features when they're more than six years old, they just go away completely and portions of your car get bricked. What a load of crap. I see Mercedes cars from the 1960s on the road frequently. Mercedes cars made today will never become classics.
