In this segment, I would pick the M3 because it churns out comparable horsepower from a smaller engine.The CTS-V competes more with the M5 and the E AMG. It's as big as those two and as powerful as those two. Cadillac itself touts the CTS-V as a competitor to the M5 and E AMG. The only difference is the price.Unlike the S63 where it felt like the car was being operated by remote control, the C63 feels much more direct. When driving hard, the exhaust note is loud and raucous and never lets you forget what you have at your disposal. Around town it's more subdued but still more aggressive and deep sounding than the screaming M3 under similar conditions. The S63 offers very similar performance capabilities to the smaller C, but oddly doesn't feel as fast. The active body control of the bigger car keeps everything on such an even keel that you lose much of that feedback on which you normally rely to judge speed. The steering in the C63 has decent if not exceptional feedback about what's going on at the front corners. The 18-inch Pirellis provide tremendous grip and the chassis feels nicely balanced. The traction control and stability control also don't intrude as aggressively as on most other Mercedes. Punching the gas through a corner kicks the back end out and let's it hang there without jerking the car around. The C63 is a genuinely fun car to drive on a twisty road, though ride is a bit on the harsh side as we discovered cruising on some of the nastier roads around these partsthe IS-F has a faster transmission and handles much better. both things which are more important to me than extra tq and hp.overpriced corolla? your comments show just how utterly little you know.The C63 is equipped with all the usual amenities that one would expect in a $67,000 (as tested) car, such as heated leather seats, dual zone climate control, rain sensing wipers and more. In the glove box you'll find an iPod connector that goes straight to the audio system. Normally this is a good thing that allows the iPod to be controlled from the head unit. Unfortunately, Mercedes engineers seem to have overlooked one major detail. Nowhere in the clumsy menu structure of the Mercedes COMAND system is there any interface to actually control the iPod. You have to unplug it, select a play-list and then plug it in to play. 
Overall the C63 is probably the best drivers car in the current U.S. Mercedes lineup. If only it were available with a good manual gearbox, we would be completely sold. As is, the C63 is a reasonably sized sports sedan with an outstanding engine. Europeans also have that aforementioned station wagon body style, which would make this a great high speed road trip machine. Acceleration to 60 mph goes by in the mid-four-second range and a C63 won't find itself outclassed by many other machines, especially those with four doors and room for four (five in a pinch). Anyone considering an M3 who doesn't really want a manual gearbox should take a look at the Mercedes Benz C63 AMG. This one truly is a viable alternative.
