Hi.
Hi, are you interested in my bike?
sure am. How are the tires, worn , like will they need to be replaced?
They are in good shape. The whole bike is in very good shape. 
Well that is great. Would you be willing to come down at all in the price?
I could, a bit, if you were to pick it up yourself. What were you thinking?
How about 161, and I would come and get it...?
I could not go that low, I could go 170, but throw in a warranty. How is that?
