Example Input: Seller: Hello, are you interested in this Cadillac?
Buyer: Yes. Mechanically is it sound?
Seller: Yes, the car is in good shape, but it needs a little work. The engine light is on, and I think it's an 02 sensor.
Buyer: Are you willing to negotiate on the price?
Seller: Well, I priced the car with the consideration that it probably will need around $1,000 dollars worth of work over the next few months, so I think $3600 is a fair price.
Buyer: In the condition it's in and then having an engine issue, that seems really high. Bluebook is showing more like $2000 but that does seem a little low to me. Maybe around $2400?
Seller: If you're willing to come pick the car up, I'd go down to $2600
Buyer: That seems fair. I'll go $2600
Buyer: 
Seller: Okay, great, I look forward to seeing you.
Seller: 

Example Output: car

Example Input: Buyer: Hi, I'm interested in the headphones you're selling.
Seller: these headphones have been used a couple of times, so they are almost like new. if you are a traveler these would be great for you as they not only provide audio, they also are noise cancelling. $150 and they are yours!
Buyer: I'm sorry, but I'm on a budget right now and I've seen a few other pairs I'm interested in. I'm looking for something closer to $105
Seller: i'm willing to work with you a bit. these headphones have a lot of features though, and they provide audio whether there is battery power or not. If you give me $135, i'll let you have them
Buyer: How about $126? That's about all I can spend.
Seller: if you come and pick them up, you can take them off my hands for $130. you won't regret it.
Buyer: Deal. Thanks for working with me on the price.

Example Input: Buyer: hi I am interested in your Nissan 
Seller: You've got great taste in cars. This was my baby but it needs a new owner and I would love to sell it to you. Got any questions for me?
Buyer: Why are you selling her, does she need any repairs?
Seller: She just doesn't suit my needs anymore - My family has grown by 2 so we need something reasonable and practical. No repairs needed at all. I've taken GREAT care of her!!
Buyer: She is a beauty I can give you 5600 for her.
Seller: Yes she is which is why I know her value and 5600 is way too low for her. I can knock off  500 and sell her to you for 8K
Buyer: The most I can pay is 7k
Seller: I'm sorry but 7k is too low. Make it 7500 and you have a deal. Its quite a steal at 7500.
Buyer: Ok I will give you 7500
Buyer: 
Seller: Deal. Nice doing business with you
Seller:
