This is a common question that consumers are taught to ask. If I have any suspicions or concerns when buying I ask the same question. I think it's a good practice to follow. I respond to these questions honestly, as I believe in full disclosure. "I purchased this bike with the intent to resell, I did this, this and this to the bike." "I purchased this bike because I am aware of it's value, it is in the exact condition that I recieved it, you may restore it as you see fit." If a seller is offended by this question he may well keep his "widget" and move on to the next.........

I sell complete bikes, framesets and parts. I enjoy finding this stuff, learning about it and finding an appreciative home for it. Not to mention a little scratch on the side.

Honesty IS the best policy.
