Welcome to Swedespeed! Just curious, what made you change your mind and switch from a C230 Kompressor to a S60 2.4T? I haven't driven the C230-K, and have not really been keeping up with its sales figures.
The C230K is a great car to drive, with great handling and plenty of grunt. The main issues were with reliability, the inability of the service dept to fix things the 1st, 2nd or sometimes more time, and the complete brain donor service manager at the dealership.
I miss very little from the MB, we have a lot more car for a little more money.
