I alway used to love red cars and went through a phase where I'd have nothing else (a bit like the white phase that I'm in right now!)
I never considered having a red C63 but this looks quite sharp - I've never seen one in real life though and wonder if in reality it 'cheapens' the look of the car. Red is a hard colour to get right - the Italians do it well be it on a Ferrari or an Alfa (especially Alfa's with their special 8C red paint) but so many other red's just don't work very well.
