The previous gen C-Class was not Mercedes' finest hour. Chief amongst its non-virtues: base engines that offered little in the way of functional power, refinement, fuel efficiency or brand faithful character (e.g. the 1.8-liter blown four). The fourth gen C300 (W204) put paid to that-- and how. In fact, the new C may have finally have broken the bigger-is-always-better mold that the German carmaker has deployed to lure Benz buyers up the ownership ladder. Ah, but does that mean that the new, more highly-horsed C350 is so superior to the C300 as to steal stars-- and sales-- from its cheaper stablemate?
