Task: Dialogue State Tracking
Input (English): Buyer: Hi there! Is your vehicle still available?
Seller: Yes, this absolutely gorgeous BMW is still available, but I'm certain it won't be for long!
Buyer: Great! Is all of the paperwork up to date?
Seller: All paperwork is up to date and I have clean title in hand.
Buyer: Sounds good. Would you be willing to pay for a background check if I make you an acceptable offer>
Seller: I have a Carfax report for it in my possession if that is what you are speaking of. 
Buyer: Yes, that's right. I recently saw a similar model at a dealership for about 30,000 but yours looks better maintained, so I'm happy to make a higher offer for your car. How does 31,500 sound?
Seller: According to Kelly Blue Book value, I have this car priced very close to the value.  Given the pristine condition, year, miles, etc. $31,500 is very low.  I will accept $43,000.  Even at this price, you are getting an awesome deal!
Buyer: What if I pick up the car myself? Could you do 35,000?
Seller: Sorry, can't do it.  
Buyer: I'm sorry, it sounds like our budgets are just too far apart. Good luck with your sale!
Buyer:
