I can’t disagree more truthfully, and I say this as a previous W204 owner. The W205 looks upscale and delivers the “wow” factor to younger people like me in a way the W204 never could. Yes, build quality is perhaps not as good as the W204 but it advanced the game in other areas.
Also let’s not forget the W204’s interior was nothing to write home about pre-facelift; it was commonly criticized here in the U.S. for being cheap. Add that to the C300 4-Matic’s (pre-facelift) tendency to suffer transfer case failures and I think the W205 is just fine.
