Seller: Yes in good condition and no there is no rust.
Buyer: Cool, is your price fixed or can you come down some?  It's a little out of my price range/
Seller: You can make me an offer if you'd like.  I am pretty firm on the 3000 range, I could come down a tad bit.
Buyer: I have $2280 cash, I could come get it today.
Seller: $2280 is too low.  Could you do more like 2750?

Example Input: Buyer: Hi. Is your sub box still for sale?
Seller: Yes it is.
Buyer: The picture isn't visible. Can you tell me what color it is?
Seller: Yes, I'm not sure why the picture isn't visible. The box is stained in a redwood semi transparent stain.
Buyer: Cool. Did you build it?
Seller: Yes, it is a custom design. I did have help with the fabrication.
Buyer: Any damage to it?
Seller: No damage at all it is still mint. 
Buyer: Sounds like it might work for me though I was looking for something a little bigger. How $25?
Seller: I'd really like to get at least 45 for it. It is in mint condition. I can deliver it wherever you like.
Buyer: No problem picking it up if you are nearby. I'd go that high only if you included on eof the Alpines. I can go $30 if you help install it in my car.
Seller: I would be willing to do that, so long as you pick it up. I can help you install. 30$ will work.
Buyer: Sounds great! I can pick it up tonight.
Seller: very good

Example Input: Buyer: Hello do you still have this car?
Seller: Yes!  It is still available and I'm interested in selling!  :)
Buyer: Can you tell me anything about it
Seller: I am the original owner, bought it new in 2006.  Great vehicle - has never left me stranded.  The interior is nearly pristine and the exterior looks very good (some dings like you would expect from an 11 year old vehicle).  Still drives great.  Only 85,000 miles.
Buyer: Ok, how much are you asking?
Seller: I'm asking $7800.  I bought a new Escalade and no longer need this one.
Buyer: Ok, I will offer you 4600 for it.
Seller: Uh, no.  Book on it is $8300.  I'm already below that.  I'd be willing to consider an offer that is more reasonable, but $4600 is over three-thousand below my asking price.
Buyer: Well to be honest I found the same care with less miles for cheaper.  If oyu are willing to throw in a warranty and deliver it for me I will offer more.
Seller: OK, I can offer a 1 year warranty and will bring it to you, but I need you to make an offer.  
Buyer: Best I can go is 6900
Seller: Make it an even $7000 and you have a deal.
Buyer:
