Task: Dialogue State Tracking
Input (English): Buyer: Hi! Is the Impala still available?
Seller: Hello!  Yes it is.
Buyer: I'm interested! How many miles does it have on it?
Seller: The car was owned by my elderly parents who drove mostly in town.  It has 75,000 miles on it.
Buyer: Great! Has it been in any accidents?
Seller: No, it has not.
Buyer: Are there any problems with the car that you know of?
Seller: No it has been very well cared for and all maintenance has been done regularly.
Buyer: I hate to sound nit picky, but did your parents smoke in the car or have pets in the car?
Seller: I totally understand, no smoking and no pets.
Buyer: Cool. I would love to purchase the car from you, but $4900 is a little much for me. I really only have $3400 to spend. Are you willing to come down on the price?
Seller: I understand your situation but unfortunately I can only come down to $4500.
Buyer: Oh no! I would be able to do maybe $3800, but that't my limit, I'm afraid. I can come pick it up wherever! I'll even bring you some cupcakes!\
Seller: I'm sorry but of the great condition the car is in my absolute lowest is $4300.
Buyer: Damn. If you change your mind, let me know!
Buyer:
