Task: Dialogue State Tracking
Input (English): Buyer: Hi, says you've had it for 20 years. Do you know how many owners it has had all together? Do you know if it's been in any accidents?
Seller: I don't know all the owners. It hasn't had any accidents in the last 20. It is a great value.
Buyer: You said it took the starter a bit to catch? Any other mechanical issues?
Seller: None that I know of. You might not need a new starter. You can have a mechanic check it out if you want.
