Buyer: HI I am interested in your bike but I am only 5'4" , do you think I could hande it?
Seller: The seat can be slightly adjusted, so it should be fine.
Buyer: Ok. How is the condition? Any scratches, dents or bad tires?
Seller: The tires are brand new, so no issues there. The frame has some tiny scratches, but nothing structurally compromising.
Buyer: That sounds great, I would like to offer you 100.00 for it and I could come get it today with the cash.
Seller: I'm afraid I can't go below 150; the tires alone cost me $50.
Buyer: Ok, more than I want to spend but since it is in such good shape, I can give you 150.00
