While I'd probably agree with Shaun that the blue is the prettier dial, there is just something so 70s and so right about the fumé dial and the orange highlights that does just work.

These are still something of a forgotten Carrera compared to the rest, but it's always good to see more people getting into them. They were a slow grower on me at first, but I really like them now - I think the dial is the initial clincher, then the rest grows on you with familiarity. Good luck with your new purchase!
