Question: Seller: Hey, how's it going? I take it you are interested in the bike?
Buyer: Hi, it's going good. And with you? Yes, I am interested in the bike.
Seller: I'm doing good! Let me tell you this bike is a decked out Santa Cruz Chameleon Custom. You can come take it for a ride and I guarantee you will fall in love with it.
Buyer: I would like that, it is a bit of a drive for me. Can you tell me, has this bike ever been in an accident? Any marks or scratches?
Seller: Never crashed it and no marks at all. It's only about 3 months old. I'm looking to sell it for $850
Buyer: Can you tell me, are the extra set of street tires new? How much tread is on them both?
Seller: The tires on the bike are in great condition. The extra set was only used for about a week so they are basically new.
Buyer: How long have you owned the bike?
Seller: 3 months.
Buyer: Are you the first owner? I am very interested in the bike.
Seller: I'm the only owner!
Buyer: Okay, great! Are you willing to come down on the price some? I am serious about buying this bike. However, like I said, it is a bit of a drive for me to come and get it.
Seller: Well, these bikes retail for $2,200 and I'm throwing in an extra set of tires. I think that the asking price of $850 is a steal. 
Buyer: That is a bit steep considering the travel it involves to come and buy it. I am serious with cash in hand.
Seller: If you have the $850 and are ready to buy, I will bring it to your doorstep.
Buyer: Could you do $750?
Seller: I could but I'd have to take out the extra set of street tires.
Buyer: How about $790 with the extra set of street tires included?
Seller: You got yourself a deal.

Question: Buyer: hello, are the tags still good on this vehicle?
Seller: Hello, yes the tags are current, and the title is clean. Just passed smog as well. 
Buyer: great, i could really use this truck but $8900 seems pretty steep for this year vehicle. an you do $7000?
Seller: 7000 is a much lower than I would like to go, this also has a after market stereo and comes with a 2 year mechanics warranty.  Can you do 8500 for all of those addons?
Buyer: hmmm... i was hoping to spend no more $8000 for a truck, ive got an older model honda that i can trade you that you could turn around and sell
Seller: Sounds good, what price were you thinking with the Honda?
Buyer: if you can do $7500 for the truck ill give you the honda, great shape and a great communter vehicle, no problems what so ever with it

Seller: Yes. It is still available and is in great condition. 
Buyer: Why are you selling this phone?
Seller: I changed carriers so I have to get a new phone from my new phone company. 
Buyer: How long have you had this phone?
Seller: I have had this phone since this version came out and have used it for the past couple years. I have always kept it in a hard case with a protective glass cover so it has no deep scratches or a broken/shattered glass. 
Buyer: Does this have a slot for a sd card?
Seller: No, it does not. but it does have great memory available. 
Buyer: Seeing as this is a older Iphone would you take $70 cash?
