Buyer: Yes. What condition is it in though?
Seller: it is in great condition.
Buyer: Why are you selling it?
Seller: We've had some financial troubles this year. Just trying to make ends meet. 
Buyer: Okay would you take $2,000 for it? sounds like you really need the money
Seller: Unfortunately I can't go that low, I'm think more in the $3500 range. As you can see from the ad, this bike has a great deal of upgrades and customization. It's really a steal at this price
Buyer: Upgrades and customization don't really add value to something if you're selling it to someone else. I'll give you $2,100
Buyer: 
Seller:

bike
