MB should maybe extend the power to e.g. 650/670 hp and offer a variable damping system.
Currently it has only the possiblity of the a sport mode which adjusts gear switching speed but no damping adjusting.
I've got this year the possibilty to be a passenger for a longer trip

and to be honest: the ride is a little bit to harsh for long distance travels (car was equipped with 19" inch rims ).
