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