Exactly, if you want a balls to the wall performance ride, the Z06 does every performance category BETTER than a C63. Whereas the C63 is really limited to putting your foot down and going straight. Sure, it turns, just not like a Z06, or an M3.
The CTS-V is much closer to the C63 than the Z06 is to either. The CTS-V is also getting some big respect in the handling department. Comparing those two at least makes sense.
You liked the C63's steering feel? To me its numb. Hmm, over an M3? I don't get it. Regardless, these two cars are completely different, but if I wanted the fun factor, Z06. Practicality, C63. Really, I'd just get an M3.
The C63 is an underrated car in my opinion. It's not just about going in a straight line (though that's highlight of the car's strengths). It feels perfectly fine in the corners to me, and I'm a fan of how easy it is to perform throttle-induced oversteer.
When I said I liked the steering more, I was referring to the directness of the steering ratio (tighter ratio than the M3's from what
I could tell), and the weight of the steering. The M3's was too light for me (but still amazing).
Comparing the cars again, I still feel that the sound the C63 makes is just out of the other's leagues. It's a very sharp, loud, in-your-face noise, which I like, but that could be due to my age. I want the car to shout "look at me, I've got more horsepower than I should ever need", if I'm dropping that kind of money on a super sedan. If I were older I'd prefer the "tamer" looks of the M5 or CTS-V.
Ok my converstations go way off topic and have little structure to them, sorry, haha. My main point is that the C63 is a car that gets looked over now because you have the surgical M3 on one side, and then you have the CTS-V on the other side, which is now considered the powerhouse of the bunch.
