trek y

Hi all, Hoping you guys might be able to help me with some sort of idea on what my Trek Y3 and Scott G-Zero bikes would be worth?.....We are selling up as no longer use them?

Here is one of the superlite carbon models of the Trek Y frames, becoming harder to find these days hence it being the only one on the web. No cracks, dents or serious damage just a scuff on 1 side of the frame and few various marks as expected for a bike of its age. Everything works, OK not...
