I don't care how many factory trained techs are used or where the parts come from. The term "factory rebuilt" only refers to parts distributed by dealers of MBNA (in the USA). Those stating otherwise are promoting a fraud. This is no less an infrigment on MBs reputation than if one sat there reboxing/selling Tiawonese parts in boxes marked with the MB star stating made in Germany.
The distinction is important and is worth a lot of money.
