Example Input: Seller: Good morning. I have a great deal on a 2007 Jeep Liberty. Tires good, AC good. Interested?
Buyer: Yeah, what's the mileage on it?
Seller: Well, can't tell you the mileage as I don't know and I'm not the type who lies. Asking $4700. 
Buyer: Have you had any maintenance problems? Does the oil get changed regularly?
Seller: No maintenance issues. Oil is changed every 3000-4000 miles. No tough or dirty driving. Only used on paved roads. It's still sharp looking (silver) with no body damage other than the usual paint chips on the front end (rocks from road, etc.).
Buyer: How about $4400?
Seller: Hmmm, How about $4700 and I'll cover $300 of non-maintenance repairs for one year?
Buyer: I can do $4,500.
Seller: Ok. I can live with $4500 for an "as is" sale.
Buyer: Okay perfect.
Buyer: 
Seller: 

Example Output: car

Example Input: Seller: Hello
Buyer: Hey, is your car still for sale?
Seller: Yes, definitely. And it is a great one. Runs perfectly. CARFAX one owner. No accidents. Bluetooth Media. 
Buyer: Hmm, that sounds great!  How much do you want for it?
Seller: I would like 13,500 for it. But I am willing to negotiate on that but can't come down too much. 
Buyer: Well, it says on the ad it has 100k miles on it.  It's a nice car but that's quite a bit, honestly.  And it's already 6 years old
Seller: That is the dealership maintenance package which is good up to 100,000 miles. The car only has 34,000 miles on it and is a BMW i series.
Buyer: Oh, I see I need to work on my reading comprehension.  Well, I only have 10000 right now
Seller: The Kelley Blue Book value is 16,500 so I would need at least 12,000 and I can give you a month to come up with that. 
Buyer: If you fill it up before I get it I'll do it.
Buyer: 
Seller:

Example Input: Buyer: Hello, I am interested in learning more about the condition of the home theater system
Seller: It is brand new and in great condition
Buyer: Great, are you flexible on price? This is an older model, so I think $40 is fair. 
Seller: I wouldn't take less than 75, they are a very good brand
Buyer: What if I picked it up myself, and threw in a JBL speaker set, could you accept 50 then ?
Seller: It is for pick up only and I have no need for a speaker set.
Buyer: So there is no real flexibility or negotiation potential to come down below 75? Work with me here, I know that this is a good brand, but the box is beatup and you could simply resell the JBLs just like these. 
Seller: How about 65? 
Buyer: Agreed, deal.
Seller: 
Buyer:
