Thanks very much for the explanations. The braking system I was referring to(not certain whats it called) is where brakes are applied in anticipation, based on driver pedal pressure and rapidity of pedal movement. My recollection of driver complaints was too jerky when trying to feather the brakes in stop&go traffic. Some claimed overly sensitive. However, that being said, I'm concerned about down the road troubles with this setup as car ages, seeing as I keep a "good" car at least ten+ years. I'm was shying away from buying my friends 04 Eclass. Mentioned this to my MB salesman friend and he said I shouldn't pass it up based on this concern, said its not an issue. Some of your comments seem to share this concern, however I was unaware of the extended warranty gesture from MB.

Thanks again...
