....and here is a snip-it from an article from C&D:
"....What really killed the Benz's chances of upsetting the M3, however, was its harsh ride. At low speeds, the suspension seems overly damped; the C63 dutifully tracks every lump in the pavement to the detriment of the jostled occupants. As the speeds rise, on back-road two-lanes, for example, the problem disappears and the Benz feels extremely capable and secure. But at even higher speeds, on unlimited sections of autobahn, the bucking behavior is back. It never caused the C63 to feel unstable but was nevertheless clearly the worst of the three cars.
In the end, we found the C63 to offer the most special experience in this highly desirable trio, but as the days wore on, we became slightly less enamored with the Mercedes' aggressive behavior and looks—the creases, the bulges, the vents, and the gaping front fascia could almost pass as an aftermarket job in this tasteful group. But if you like to be seen, heard, and talked about, the C63 is your Lamborghini of sports sedans."
this is another fun video....even Tiff had difficulty controlling the C63....
For the impatient...fast forward to 6:20.....and if you want one quick visual for the comparison of these two cars....fast forward to 7:55...
