How are you doing?
Very well thank you and yourself
Great thanks,  Are you interested in the bike?
Yes I am. Is it used? how long if used?
It is lightly used and in great condition, Listed at $200 but willing to negotiate a little.
Does it work very well like new?
Yes everything is tuned up.  make me an offer
$120 is what I can pay at the moment
I can't really go that low.  I can go $175 and deliver the bike to you.
How about $150?
Yeah, I think I can do that
Great then thanks!
