Seller: Hey, are you interested in the bike I'm selling?
Buyer: Yes, can you tell me anything else about it?
Seller: Unfortunately it is a bit on the older side and does need a little bit of work. But considering the condition it's in, I still think it has the potential to be a great bike with a little work. Hoping to get $250 for it.
Buyer: I'd love to have it would you be willing to come down to $150 since it needs some work?
Seller: That's too low for me. How about this, I throw in a new comfortable seat and scrape off the rust, and we go with 230?
