Black chrome emblems and carbon fiber interior

I just recently purchased a 2002 Lexus 1S300 along with the Black chrome emblems and carbon fiber interior. I've been reading IS300 forums and seen to realized that the dealer might have ripped me off on the prices for the black chrome emblems and carbon fiber interior pieces.
They charged me $1100 for both the Black chrome emblems and carbon fiber interior, roughly $550 each.... Does anybody know how much they invoice / retail cost actually is?? Coz I'm not too happy at the thought of being ripped off... Please reply, thanx
