Selling parts from my 07 A3 Sport, help!

[J7-AUDIA3]

Hi Guys'n'Gals

Looking for some input as I've never sold motor parts before. First of all a list of what I'll be selling;

Audi In Dash 6 CD Changer (Double DIN)
Audi A3 Sport Front Bumper
Audi A3 Sport Front Grille
Audi A3 Sport Front Fogs
Audi Multi-Function Steering Wheel

as title says, all from my 07 A3 Sport. What I'm wanting to know is, what would be a decent asking price for each? And is it better to sell via Classifieds or EBay? Oh yeah and if anyone would be interested in anything.

Would be happy with any help at all people, thanks.

Jay
