This is a silly thread.
The F30 is a new platform with later assembly techniques and being compared to pictures with assumptions that the pictures elude to build quality compared to the aging C class MB. Just silly.
example: The C has an outdated sound material stuck on the door panel and as you see the F30 has the sound material actually molded into the door panel itself.
Stats like reliability(skewed when comparing new launches to old models) and measured sound levels. See that is a bit more scientific.
