Input: Seller: HI what kind of shape is your bike in ?
Buyer: Hi I'm interested in the Trek it's definitely got some wear and tear. I'm willing to buy it for $40. I'll even come pick it up.
Seller: well I meant to say that my bike needs a bit of work for the shape that its in..but it was really expensive when I bought it...how about 70
Buyer: 70 is still too high for me it would have to have some kind of extras for that price. What makes it worth 70?
Seller: It has the 4130 frame which is really sturdy and I just put new tires on it last month..all you really need is brake pads to get it perfect..how about 65
Buyer: 65? I'd do that if you could deliver it.
Seller: I don't drive unfortunately..i just ride bikes so you would need to come to me
Buyer: I'd do 60 then and I'd come pick it up.
