The only 'special edition' of the CC that i'm aware of is the Roland Garros special edition. These came (as far as i know) in either a silver colour with a tan leather interior or a dark metallic green (similar to British racing green) with a green and tan leather interior. Other than the seats having the Roland Garros embroidery, they were identical to any other CC, being able to be specced with heated seats, cruise etc etc. They also came in both the 1.6 and 2.0 petrol engines only, again as far as I know.
So no, i don't think yours is a special edition as such, but if its special to you (and it certainly sounds like it

) then that's fantastic!
The Roland Garros cars carry no real price premium over the 'standard' cars in any case.
