Input: Buyer: I am interested in your bike. Is there anything wrong with it?

Seller: A little, make me an offer.
Buyer: I have looked up what this bike is worth and taken into account the new handlebar tape and tires and I would feel comfortable paying $700, would that work.
Seller: That is a little low, I understand it needs some things. I would drop the priced to $1,000.
