I thought the adaptive damper was standard on the M135i?
anyway dont listen to sales person again, they always say you dont need to break in because they dont provide break in oil change, thats all
if you are planning to keep the car, spend a week or two to break it in, just dont push it thats all
then spent the money to get the proper oil change to some nice oil, you will appreciate your own effort afterward
anyone looking to modify the car already?
I am looking if the N55 mods will all fit the same
