It's not an individual color for 2013 in the US. It is shown as a regular metallic in our configurator.
I don't think it's that bad, and I'm comfortably under 80
Not saying I'd order it, but I think it's nice to just see something on the forum other than white, black, Estoril Blue II, gray, EBII, red, or EBII for a change
BTW BMW apparently thought enough of Orion silver to use it in the press photos of the E89 Z4. Looks a bit lighter and more silvery than your standard Camry/Lexus/Minivan beige, though I keep thinking they could swap one letter and call it Onion Silver, would be more descriptive...
