Task: Dialogue State Tracking
Input (English): Buyer: How long have you had this car? I am interested.
Seller: I have owned it since 2002, so 15 years. I'm the original owner.
Buyer: Any accidents, dents, or marks?
Seller: No accidents or dents. The paint is in decent condition. It is the original paint job so it has some wear and tear.
Buyer: Would you accept $1500 cash in I will get it today since you had it for 15 years which is a pretty long time 
Seller: I'm sorry but I am not able to go that low. I'm willing to work with price but not that far. Would you be more interested if I threw in a Alpine stereo to replace the stock radio?
Buyer: Yes how about $2750 cash
Seller: $2750 in cash sounds good. We should be able to finish the transaction quickly. Thank you.
