Hi! are you interested in the bike?
Hey there!
Yes I am! It seems like the perfect bike for me! And I'm in need of a racing bike!
Great. Do you have any questions about the bike?
The only thing wrong with it is the paint, correct? It functions well, right?
Yes, It has very minor chipping, but other than that great conditions. Gears are fine, tires, are fine, seat is great. 
Awesome! I would love to pick it up today in a few hours, would you take $650 in cash for it?
Great! I will be home then. Can we do $675?
