hi, my brothers car caught on fire 2night and owning 2 mercs myself i convinced him its time to get one. the 190d 2.5 i have is a very good car, reliable and economical. what are the c-class diesels like? i heard bad things about the 220, but the 250 i heard is suppose to be good. how similar is the engine to my 190's? and is it likely to be as reliable or are electrics a problem? thanks alot
