Here is the test summary of Car Mag review:
The immortal F1 was always going to be a hard act for the MP4-12C to follow. The F1 was a seminal supercar and one that is impossible to forget. It casts a dark and very long shadow over the MP4-12C. But that is unfair. The newcomer is vastly cheaper and cmpetes in a very different segment of the market.
By all measurables standards, McLaren has achieved what it set out to accomplish. But supercars are just as much about the immeasurable. And here the MP4-12C does struggle: in terms of the more superficial, subjective measures of looks (pretty, but rather generic) and sound (uninspiring, even with the sports exhaust), it left some team members cold. That said, it's sublime in the way it delivers its performance and, for the capable driver, there are lots of entertainment and satisfaction to be had. Simply put, we haven't tested a finer supercar. It's now up to Ferrari to prove us wrong.
