Seller: hi
Buyer: Hi, I like your bike. It reminds me of one I used to own back in the day. I would jump it off ramps while rocking a TMNT t-shirt.
Seller: its a nice bike normal wear and tear
Buyer: Is the chain rusty? It looks as though it hasn't been greased in a while.
Seller: no rust but it needs a brake
Buyer: The asking price is fair, but I think it's a bit high. I'd like to pay $150 for it. If you do the $150, I'll perform some awesome wheelies for you before I leave.
Seller: it is 27 years old you can not find these anymore, how about $170
Buyer: You're right, those bikes are hard to come by. How about we meet in the middle and do $160?
Seller: $165 is as low as i can go
Buyer: If it had the original wheels, I would do the $165. But I need to stay firm at $160. It's a good compromise I feel.
Seller: You are right about the wheels, ok $160
Buyer: Deal!
Buyer:
Seller: Ok
Seller:
