Hi,
My car is an auto and has this option (vehicle dynamic package)with the sport button below the radio and after looking online mercedes say it also has dampers that adjust automatically with this option and if you ordered new shocks and springs they would be different to a standard set up and the button is not just to hold gears for longer but so many threads give different answers
