For those who have questioned what interior and top color combinations can go together with the 2010 Roadster, here ya go (I apologize if this info has already been posted, I put the list together as I needed to know myself).
Code:
Exterior color (code) | Int. - Base | Int. - Tour | Top*
---------------------------------|-------------|--------------------------|--------------
Black Cherry Metallic (NAG) | Black(G) | Black(G) Gray(K) Wine(W) | Bordeaux(X01)
Magnetic Black Metallic (G41) | Black(G) | Black(G) Gray(K) Wine(W) | Bordeaux(X01)
Monterey Blue Pearl (RAE) | Black(G) | Black(G) Gray(K) |
Platinum Graphite Metallic (K51) | Black(G) | Black(G) Gray(K) Wine(W) | Bordeaux(X01)
Solid Red (A54) | Black(G) | Black(G) Gray(K) |

White Pearl (QAB) | Black(G) | Black(G) Gray(K) Wine(W) | Bordeaux(X01)
*The Bordeaux(X01) top is only available with the Wine(W) interior.
I make no guarantees this info is accurate, YMMV, you get what you pay for, yadda yadda yadda, etc., etc., etc.
