I think I am going to need all 4 absorbers replaced (the car isnt too stable at over 100 mph and I didnt change them for several years. I am going to drive to Germany couple of times - want go over 120). How to save money on the parts? I see there are quite a few 'replacement' brands not MB branded. Is it worth to try them? Any particular brand you guys can recommend? Or shall I stick with MB branded only?
