Example Input: Seller: Hello, Are you interesting in buying my 1973 Datsun 620. It is very good reliable car.
Buyer: Hi there. Yes, can you tell me about its condition?
Seller: I've had repairs done to the car such as, removed and cleaned the gas tank, replaced all fuel hoses and water hoses and they have good Nissan Titan wheels
Buyer: Hmm. Okay. I see you've listed it for 3400, but for a car this old that seems rather high to me. Is there any chance you could go down to 1300?
Seller: How about 2,800
Buyer: That's still too high for me. 1600?
Seller: I could install other parts such as the original seat and I'd sell it to you for 2,400
Buyer: 2200, provided you have a mechanic check it out for me. 
Seller: Okay. Deal
Buyer:
