No, let's not. Every test is the same except an occasional oddball site that has no credibility, iike the one you linked or a non-car site like cnet that has no business pretending to know about anything more than toasters and iPhones.
There's no reason to give something false praise just to make people feel good, this isn't summer camp. It has issues with both understeer and oversteer due to it being nose heavy in front with limited rear grip. But it's definitely fast in a straight line and it looks decent.
I don't get why there are so many C63 people coming in here seeking some kind of validation or approval and then getting mad when they don't immediately receive it. Are there M3 owners doing the same thing on MBworld? That's silly.
