Well...I'm not going to be trite and say the colour I have must be the best - when I chose my car it was the combination of the colour, the year, the condition and the performance that sold me - and I have Blaze Red (or whatever it is - metallic red).
I think my favourite is the graphite, and at first I thought I wanted the graphite with the cedar/ slate interior, but I think the brightness of the "cedar" would get cloying after a while. I'm pretty happy with the black interior after all.
