That's awesome. Haven't had a chance to drive one yet. On the AMGs exhaust note-I do like now loud it is but that's it. It doesn't sound good. I love with the standard M3 exhaust and on the perf exhaust how the sound different and have different pitches between starting up,idling, driving, and flooring it. With the C63 it just seems that it sounds the same no matter what. Another thing I have noticed with AMG is how quick they come out after the normal model. The new ML SUV came out just a few months ago and now the AMG version is out as well and similarly with the C class. It takes years to get the M out.
