going rate for mazdaspeed parts?

[Johnerz]

I was just wondering what sort of prices are being paid for certain mazdaspeed parts.  i have a mazdaspeed rear wing, side skirts and dials.  pics are here:

i was thinking of changed the skirts for re-a skirts and carbon brake ducts.  havent decided on the rear wing.
 
this isnt me offering the parts, just wondering what people reckon they may be worth, or what people have paid for them in the past. (the rear plastic sun screen is not on the car any more)
 
cheers.
