Mercedes C63 AMG Black leaked

Ever since the C-Class Coupe was launched we've imagined how will the Black Edition look.Well its not that black as you can see in the (leaked) pictures.Actually is as red as possible.
There's a storm of speculation coming:-some say that it will have four seats
-some say that it will be more friendly with the passengers(friendly meaning more comfortable).
-some say that it will be produced in unlimited numbers(hard to believe, in my opinion will be a limited edition.)

There are pictures that the Mercedes officials didn't want to be posted on the internet so there are no official information.There are rumors that the weight was reduced by 40 or 50 lbs and that the engine will be the traditional American V8 of 6.2L(now producing 517 HP and 640 Nm of torque.(0 to 60 in about 4 secs).
It won't be long and the official pictures and data will appear so until the official update we'll have to be content with the following pictures.
I'm really curious what would you choose between the C63 Black and the M3 GTS.
