Nice pics and description of W204 technologies... alas much of these (Presafe, adaptive brake lights, etc) are not coming stateside. But still good read.

Presafe is standard in Australia for all C Class, except the flashing rear brake lights during emergency braking, our government authority believe that flashing brake lights would confuse the people behind and "Follow The Light" straight in you.

I now know why we pay more in Aus for a C Class then the people in the US, money well spent.
